I saw on BanksPower.com the Chevrolet diesel truck, the "D-Max Type-R", and they used the Nascar Chevrolet chassis for the base. Well, is there any ways I could buy plans for an older version of Nascar's Ford chassis? To drop my own engine into, and basically start from scratch.

 

You would probably be better of buying a chassis from Hutcherson-Pagan or some other mfr. and starting from there. By the time you get done purchasing the tubing, fitting it, checking for straightness, etc., you'd be ahead of the game with purchasing one. They build their chassis on jigs, so you know everything will be straight. I wouldn't think a bare chassis would be that expensive either.

 

This is the site you need. I can spend HOURS going through all the stuff they have. I have some relatives selling some modified chasis's there.
