Thanks Dingus, I'll look into that. I see You have a 60 Chevrolet. Do you have the original frame under it .I have concerns about the 58-64 frame . How much horse power can it stand? Do you or do you know anyone with a big motor in one? I know about all the original motors ,but I wonder how much motor the stock frame can handle? I am putting a 6 speed in my 64,so the tailshaft will be further back. I would love to think I might be able to use a 1 piece driveshaft but I have my doubts.Thanks!
