Barn find! Sadly not a Mopar. Still cool
Yep, parts are out there. A good friend of mine built one for his wife, late model 5.0 factory F. I., 5 speed, disc brakes & A/C. By the time he finished it about 6 months ago, he said he had over 40K in it & that didn't include the purchase price. He has never told me what he paid for the roller.
