As I say the only part that I think makes a difference is where the body rests on the chassis. I can't see 50mm making a difference any where else.

You can just about see on this pic where the body on the iside curves around and down to rest on the top rail.

Fair enough, hopefully it wouldn't crack/damage the bodywork stretching it over much. Although is the bodywork strong enough as I'm guessing you'd have to be quite carefull getting in & out of the car and wouldn't really be able to put any weight on the side?

I don't think there would be any stretch. It just rests on top so I would just weld in another tube on the inside and rest it on that.

If it's 25mm each side it couldn't be easier.

Has anyone done this yet or checked the dimensions??

No it won't fit without a lot of work because the Roadsters track is the same as a Sierra. The Challenger was made to take the Mk2 Escort axle or IRS with shorter Sierra drive shafts. Was never a gel coat finish either so needs painting.

I checked the dims and the haynes is 50mm wider than the Thruxton chassis.

I am currently building one but using the Thruxton chassis.

Wheelbase will be the same. Though the bonnet is moulded to allow a 50mm or so variation.

Jim Walker @ JWE will be happy to chat if you are interested.

What sort of money are they asking for the bodywork ?

I quite like Super 7 styling myself but appreciate it's not to everyone's taste so having the option of alternative body styles for the Haynes chassis would seem to be a great idea as it would attract wider interest to what we all recognise as an excellent build platform.

I've been thinking about designing/making some new front and rear arches/wings that are a contemporary cross between the classic 7 clam shells and a Morgan. You would still use the current range of nose, bonnet and scuttle but it would give a full body look. This keeps the cost down and keeps the moulds easy and cheaper to make.

I think you need to go and see these things . It looks a bit like a down sized austin healey. I remember looking at an aston type body conversion on a capri once and thought it looks ok but in the flesh it was crap.

Phil,
Keep it simple, folk don't like weird looking 7's.
