I am an mechanical engineer and in the past did strengths calculation on heavy lifting equipment. I had another look at it.
Can't completely calculate it as i don't know all the angles, dimensions, load ect but a simple approach i can do. 7/16 is almost M12. I assume it will be a higher tensile bolt then the 8.8 class so i take the 10.9. These bolts can handle a certain nominal load. I assume the M6 bolts face 60% of the load on the M12 bolt. A M6 10.9 bolt has a nominal load which is 25% of the M12 bolt. If there are 2 person in the car, the load on the bar will be twice as much so 2x 60% is 120%. If you would take 4x M6 bolts to mount the bar, this would not be enough as 120% > 100% (4x 25%)so you would need 6x M6 bolts (120% < 150% (6x 25%)) An M8 10.9 bolt has a nominal load which is 43% of an M12 10.9 bolt. So 4x M8 10.9 would make 172% (4x 43%)which is larger then the 120% so you would be oke. It is a rough calculation as the type of load on the 7/16 bolt is different then the type of load (pulling force, bending force ect)on the M6 bolts but it should be oke.
So i would advise you to use 10.9 higher tensile bolts instead of the common 8.8 bolts
I would also advise you to not use a saddle as with a saddle you cannot simple divide the load over the front and rear bolt. This because the saddle would deform under load and you cannot predict how the load is divided over the 2 bolts face but it will not be 50/50.
This is my quick and dirty approach which is not 100% right but also M6 simply doesn't feel good

I don't think M6 bolts will be strong enough (in theory). If the angle downwards after the bar is 45 degrees, the bar will face approx 70% of the load in the belt. If there are 2 people sitting in the car, the bar and the M6 bolts will face twice that value. If you compare 2x2 M6 bolts (assuming that the load will be equally divided which is not so when you use a saddle) to the thicker 2 bolts which hold the belts in the rear, then i would say its not enough. If the bolts are not strong enough and break, the people will go forward and the function of the belts in not there anymore so i can understand that the DVLA could have doubts about it.
Just my opinion and its not to criticize you . I really like the way you build this car and there are no bodges and its the highest quality one can find but you are dealing with a strange kind of people within the DVLA. I agree with Phil that it is strange that the Ronard passed

It may be a good moment to switch over to silicon brake fluid. This doesn't attract moisture so doesn't need to be renewed every 2 years and when spilling it leaves you paint undamaged. Have it in my MG V8 for approx 10 years now without any problems

You must have a lot of patient and motivation. I know there is no way back and there is too much time and money in it but iwouldn't feel good if i had to weld and cut in to this nice interior and do all the detailing again. Hats off for you!

Did some small but time consuming jobs on the Rover I replaced the BW35 by a 4ZF HP22 automatic transmission and wanted to use a Jaguar XJ40 to connect the box with the shifter but this didn't work as the cable was very stubborn. Arranged a cable from a more modern Jag which is more flexible but has the wrong mounting bracket. cut of the old one and made a new one from a piece of pipe and a plate Some time ago, i repainted the fuel tank and now i assembled the parts on the filler side. The parts were got a new layer of zinc and /or pain The fuel cap doesn't have a lock with a key but can be locked by a pin in the boot. The large diameter hoses were hardened so i bought a new piece of the right diameter Protected the paint with some duc tape as due to the stubborn inner pipe, its not easy to fit the filler cap housing This fitting took much more time then expected as the inner pipe is really stubborn. Next job was to fit the fuel lines from tank to the divider. There are 2 lines running from the tank to the divider underneath the car as the Rover has a reserve fuel option. Initially had the idea to replace the plastic lines by copper lines but the connections to the tank and divider had different diameter connections so i checked and cleaned the plastic lines and these were in good nick. I had the clips send out for zinc coating but due to rust, these were heavily pitted (see the left one in the picture) so i made new ones out of 2mm SS These should last forever.... I already had made a bracket for the fuel pump which was suitable for the copper fuel lines but i couldn't fit the plastic lines. The first version As one often faces its 2 steps forward and one back, especially with modifications (replaced the mechanical fuel pump by an electric one). I made some new brackets which gave enough clearance for the plastic lines to be fitted. Next job was to fit the rear heather (fitted underneath the RH rear seat) which was completely dismantled and all parts were zinc coated, powder coated or painted. Its a shame its hiding underneath the rear seat fitted to the car which some black sealant Bought some plastic flexible hose as a kind of idolator for the rear heather hoses which run underneath the car Ordered some oil for the ZF box. when this arrives, its time to let the engine run so a great milestone in the build.

your car looks very good. Like the arches and the front.Didn't follow your thread but looking at page 1. you did a magnificent job.

The Camino looks good! I also have good experiences with Automec. Bought a brake line kit for my Rover P5B years ago and fitted it a year ago and found 1 pipe was too long and it seemed the short brake pipe from the reservoir to the master cylinder is normally not in the kit. Gave them a call and they send both pipes free of charge

I used product from Furniture Clinic for my daily rover P5B and it holds really well, Gave the car a treatment approx a year ago and it still looks very nice. You can send them a sample and they copy the color. I was rather skeptic about painting leather and vinyl and using filler on leather seats to repair these but it works very well and it sticks well. The vinyl door cards after painting. A seat before treatment and afterwards Even holes and tears can be repaired rather good Before during the repair proces Filler applied into the gaps And after painting. Its hardly visible and also after a year of daily use. and the seats after the treatment. It can be painted with a spraygun but is isn't very citical like painting panels or the paint can be applied with a sponge. Never did this kind of work before. Takes a fair bit of time but i am happy with the results. Peter

i think pressure is lower then 2,5 bar but more is better althought these high pressure hoses are quit stiff. I recently fitted a auxilarry cooler to my trans and used hoses which were suitable up to 28 bar and these are less stiff. I bought some hydraulic pipe and made my own steel pipes and used ferrules and had some connectors pressed on the hoses not cheap. In total it costed approx Euro 200, incl the cooler good luck with your project. Its a good looking car! Peter

Didn't do much on the Rover. Fitted the radiator and the hoses, the fan and some other bits and pieces. There is not much left to install in the engine bay and i am happy with the way it looks Had a very nice holiday by taking my MGB V8 out for a trip threw Germany and France along the Rhine and Moselle. We first took the "Autobahn" to get past the industrial area called "Ruhrgebiet". As some German roads don't have speedlimits and there was not much traffic, i couldn't resist flooring it too 200 km/hr. The car has slightly stiffer springs and Koni's and the road holding is extremely good a high speeds. Although the brakes are slightly upgraded to MGB GT V8 spec, these are no match for todays brakes so i had to be careful. Soon after the "Ruhrgebiet" we took B roads along the Moselle which was nice and great fun. Not much traffic, almost no sleeping policemen it was a pleasure to drive. In Holland there are not many of these roads with not much traffic Visited some castles. The wetter was good, friendly people and good food. The car performed very well. Its such a nice car for touring and due to the Rover V8, it is so smooth and mountains are no problems. Peter

If you are worried about the current you could add an extra wire. This wire runs normally from the alternator to the solenoid from the starter motor.

Thats a thorough job. Better to do it good and spend more then do it half and also spend a lot of money. You wont have rust issues anymore which is nice to know. Seen a lot of cars which got a respray on the panels but soon afterwards had rot underneath or in the engine compartment. Will be one of the best GTI's when done
Thanks for sharing Peter

I bought my Rover P5B in the UK and brought it to Holland. As i didn't had a decent towing vehicle for a heavy Rover, i rented a single car transporter. This drives much more comfortable then a trailer and used the Eurotunnel to get over. As i needed to pick up the Rover near London, i managed the picking up in 1 long day. I think i payed approx Euro 350,- without fuel. You could also consider using Shiply which is a kind of marketplace for transport. You can drop the transport there and shippers quote a price for you. The may combine it with another shipment which could give low prices. I used it once and payed Euro 70,- to get 4 wheels from the UK to Holland.

There are company's around that make custom made handrails for stairs and these are rather fleible and can make bends and mounting brackets

Good to see the car moving under its own power. Just returned from a week´s tour threw Germany and France in my MGB V8 roadster conversion. Was great fun again, a light weight car with the V8 power. It is so relax to drive in general and especially when mountains show up, It leaves most moderns far behind. Mine has a 3,5 lit Rover engine and yours even has a better power-weight ratio with the yanky V8

i am not electronic whiz kid but i notice that modern digital multimeters some times give other reading then the analog multimeters and the way the VR units works, it could be that although your digital multimeter says the VR is oke, it could be that it isn't oke. I would replaced it with an electronic one as this is much more reliable. In my rover there is a flasher unit that works the same way but it got very hot and i replaced with an electronic flashing unit.
This doesn't explain why the board got damaged but i simply don't trust the old Vr's
