I found some nice images of a Falcon bodied special.  I took a long weekend and this morning my mate dropped round and gave me a hand shifting the body More space. Looking at the pedal box and the alloy panelling I am now more sure than ever that we have another Autotune chassis build cock-up It looks like the original builder put the panelling in as the book but then found the clutch pedal was up against the panel - he then took it off and stuck another bit of alloy on the inside of the tunnel. The reason for this is that this... ....is welded in the wrong place ! It should be as the Red Gemini. Which may mean it misses the 40's and not require twin masters..... I will have a think about that whilst grinding that plate off.

That does look to have a disproportionate amount of space right of the accelerator pedal compared to left of the clutch.
Would the brake pedal work the other side of the column, with the clutch on the left of it still?
Would be big bonus if you fit the 40s with less jiggery
EDIT: Also, Circuit des Remparts - must go back...

doesn't that plate flex underbraking?
looks like it could do with bracing to the bar accross the top of the dash.

In the Escort donor the column goes between the pedals - but higher up - The pedals have been respaced on the Gem to cramp them together on one side. Decided that it has to be a full bias set up. Will probably end up with extensive modifications to the pedal box.

will an escort bias box fit with simularly tweaked pedals or us it going to be something custom?

Hey DS, I used some of the distances off of the Grp4 Escort RS prep manual when recreating / modifying my imp bias box, since you look to be starting from a Mk2 box I thought there might be something useful here, even if you end up splitting off the B&C pedal assembly from the A, or whatever www.doublegmotorsport.com/rsprep/09-Brakes.pdf

With the body off it gave me the opportunity to have a look around...... The standard of chassis finish from Autotune never fails to disappoint - You are there with welder but rather than A- do a proper joint you B - do a curse word design of joint and then rather than weld a cap on the top - 30 seconds of welding - you leave it open and fit a bung in it. FFS that's just wrong and lazy. Then I spotted this - don't cap it off and why even bother with a bung. Which is when I notice the misaligned Panhard causing the trailing arms to rub. But hang on, why is there a row of rivets riveting nothing ? and why it that section of alloy sheets ( and bloddy awful Denso tape) there. And on the other side? So rather than adjust the Panhard - there is plenty of adjustment - the builder removes the 0.8mm alloy sheet and folds it in behind! Uh? More work to undo. One thing that particularly annoys me when having to do stuff like this is the rivet ends being left in the tubes. probably have to drill a hole remove them and then weld it up again. And the laziness just keeps getting better, why round off a bracket, or bother to correctly support a major load bearing joint. Just make it out of some totally over the top gauge steel and hope that will do it. Each of the three chassis I have looked at is different. Better order some new 3.3 drills.

I will probably go bespoke for the Gemini with the M/C's under dash. Another in a narrow footwell Ginetta G27 standard pedals also leave much to be desired but no clear picture of those and the changes I made.

Todays soundtrack for a couple of hours messing about making a mess. First off let's drill some rivets out. And yes although the holes did line up he drilled new ones anyway! And when flattened out it also lined up with the other holes so was exactly as suspected. I figured I would try and understand why this had been done, so I removed the the adjustment bush end from the Panhard. Hmmmmmm..... Let us adjust the Panhard so that the trailing links have the same clearance side to side. FFS  . The next job is to check the axle alignment in the chassis as there is nothing to say that the brackets are in the right place on the axle and they correspond with the trailing links having clearance. Oh well.

I decided to do some more checking and measuring around the Panhard issue. I looked across at the passenger side and thought to myself that panel looks flat - and this side is held off by the trailing arm brackets.... hold on they haven't... Oh yes they have. The brackets on the O/S bring trailing arms closer to the body by the thickness of the over sized brackets - which I think are produced in the cheap  way of just slicing up box section tube. It's no wonder there is evidence of our original builder losing the will. And have I mentioned my hate of this stupid Denso tape -" to prevent galvanic corrosion between the chassis and the alloy panels" - which is only required due to the poorly applied - no doubt cheap- powdercoating that falls off in sheets. On a positive note, the brackets on the axle appear to be in the right place.

probably make no difference. It will however make me feel much better. Thank goodness you have done that, DS. I don't know how anyone could have fitted that as it was without it making them feel terribly poorly afterwards.

So the trailing arm brackets were welded on in the wrong place by the factory??? If that's the case it's more than a bit unimpressive. Did they not have a jig?

James They may well have a jig - But it would be made from untreated pine, nailed together and stored in the open.... Actually its probably made from old pallets and they reused the nails.

Found half an hour before dinner to strip the O/S front suspension off - The wishbones and the rear trailing arms can now get a blast with the wire wheel followed by a dip in the de-rust. The thinking is that while this far into it I may as well pull the prop, axle, and the fuel tank and have a full stripped to the last nut and bolt rebuild ! The lengths some people go to fit new carbs !
