[wrench]

as a question to Jack21, i am considering building one of these auto's, but how much fabrication is needed? (as far as welding, metalwork). I have been a mechanic for 15 years at a dealership level, I like to think i know how all the subsytems work. (although sometimes these new %$#@ cars still confuse me, why do they have to change so much in one year?) the only thing i have not had much need for is the metal working end of the business. How much is needed on the average kit?
