Had been converted to a drag car. Still has all the stock stuff in his garage. Solid body except for an area on the bottom rear of both doors. Not on the outside, but in the "tub" of the door. Son wants it bad. Custom paint (not great, but decent) and a blow tie in it now with an AMC 290 on a stand. He wants 2 grand for it all. We would build build a 360 Mopar for it unless able to a locate a 401 AMC. How hard are these to a find parts for? Anyone make repop stuff?
