Hey One
The guy selling those plans is very helpful but, I will tell you Cliff has an exact OEM chassis replicated I mean it is exact has I had measurements from a OEM chassis in hand while my car was being built, you might want to contact him and see what he would charge as those plans do not have the upper steel work for the roof, quarters and such. I am just saying from the chassis I have and the plans I bought from Chassis works still required allot of additional fab to get all your mounting points, drop Cliff an email has I can tell you his work is outstanding.
