Taken a few pictures with some rough measurements. The first thing I noticed is that the mounts aren't flat and the pinion looks like it goes into the car horizontally.  This is roughly the height from where it would bolt up to the bulkhead.  It isn't a very nice thing really, and I;m not sure if it take up any less room than the vauxhall one really. If you need any other pictures let me know. |

Thankyou for those pics, I have been back and forth looking, checking, measuring, measuring, but unfortunately I don't think that rack in particular will work, its just too big where the pivot isand the Toyota has a water manifold on the back of the head, Looks like the vauxhall one, or possibly a VW1303, Thankyou again.

Thats OK. If you don't mind keeping the steering box could you get another arm made with a crank in it to clear the engine.

Whats the reasoning behind a centre Pivot rack rather tgan a conventional one replacinghu the drag link as in a minor? The thinking behind using the centre pivot rack, firstly its reasonably easy for me to use as the original steering runs across the back of the bulkhead above the bellhousing, and thats about the line where my rack will have to go to clear everything without having to rejig the whole front suspension/steering. Minor racks are, from memory about 4" too wide, although they are easy to narrow, at the moment I would prefer not to go down that route, another option is fit a Spridget rack, use the correct steering arms etc, again its a well trodden path, but I think the steering would still foul my carbs. More thinking behind the rack, a centre mount rack should give less bump as the arc (radius) movement is less, in turn, having less impact at the steering arm than a traditional rack. hopefully this makes mounting of the rack dead easy to get it in the correct position. which in my mind I make it on a position to mimic the centre drag link, obviously I will perform bump testing, rightly or wrongly I don't envisage any major problems. I always thought the best way was to try to get the steering arms on the rack the same length and parallel to the suspension arm, that way they move in the same arc and therefore there is no relative movement and no steer effect. |

That is the general way of setting up a rack I can confirm is is a right PITA to do too, not only is it up and down movement its fore and aft movement too, adjust one and another one comes into play, such a palava to do, go too far one way and everything goes out of sync and the bump steer comes back, it is not as straight forward as just aligning the pivot points, using the centre mount hopefully will make aligning everything a lot simpler as the arc of the steering arms is almost negligible over the 3" of suspension travel I expect.
Saying that, these racks would not exist if they did not solve a problem, the problem is what, I don't know, but there are a few cars that have them, Imps. Pug/saxos, 1303 beetles Various vauxhalls, Mazdas, Imps being the only one with wishbones,

Honda Civics have a rack like the Vauxhall ones with the centre pivot. Also have electric motor assisted steering so the rack should be smaller with no PAS fluid pipework  Loving the look of this build though, and the fact its a van  |

Would bike carbs at a slight angle help with packaging? Would bike carbs be an option? They are generally less bulky than webers...? Great minds eh? ;p Looking good Ian, enjoying watch this come on |

Ah that's what I get for not reading every post I've got a set of bike carbs in my garage doing nothing Ian if you fancy them, I'll have a look at what exactly they are, I've forgotten |

After a bit of a Palava I have just received this rad in the post, Big thanks to Spongebob, its for an EG Honda Civic, I cant believe how well it fits the Austin, could almost be made for it,    Engine mounts are sort of made, need finishing but the basics are there,  Gearbox mount was going to be the stock corolla one but I have just noticed it has delaminated on one side, rubber from metal, as I an using stiff engine mounts and the gearbox mount is a cradle so the box can never fall out, can the mount be reattached using Sikkaflex 221 ?? or similar |

A company I did my apprenticeship at used to make rubber bonded to steel mountings for one of their customers. Used to use a product from loctite that was a purpely grey colour. Used a polyolefin primer. Used to coat the two steel parts and the rubber,wait to go off,then press together. Stronger than a strong thing being strong. Rubber used to tear before the bond gave way.

how much space is there from the back of the engine to the bulkhead?
the 106/ax/saxo racks are mounted at an angle, the pinion entering the cabin at roughly 45 degrees, bulkhead is shaped around the rack body, maybe you can do the same to your bulkhead to give more room?
if there's cooling gubbins back there it shouln't be hard to alter them surely?

oh yeah, I'd happily have the wheels back too I sold them a few years ago and they've been through at least three owners that I know of! as long as they've been straightened up that is. as you said, that specific casting is bloomin rare |

How much space behind the bulkhead, hard to say as the bulkhead is the same angle as the toe board, which is about 45degs I would guess there is about 75mm where I need to mount the rack,

Would an angled spacer between carb and manifold solve the problem ?

or a different inlet, shortening is not a wise idea overall, you do need to retain a reasonable inlet length.

An angled spacer has been thought about, but to get the carbs to fit, they would have to be about 45degs I also looked at Ford Crossflow dogleg webber manifolds and making and adaptor plate, I think I would be better off using downdraft carbs, finding a downdraft manifold will be a challenge too, especially as I can even find a photo of one for reference.
