That's so cool.
I want to do somethin like this for my dad after I graduate school. His favorite car was a 1st gen mach 1 and he'll never have a chance to own one... he's not into cars and would never pay for or build somethin himself. I've been having this thought in my head for a while, take an old base model driver 69/70, swapping for a new engine and giving it the mach 1 paint/body treatment
