I used a 350/350turbo and a 57 pass car drive shaft bolted right in after I changed the 57 course spline for the fine spline.Other times I've just gone to the wreakers and some of them have piles of drive shafts,so I just picked one that was the right length.Usually they just gave it to me as they know me,I have paid as much as cough,cough$10.00 Canadian(that's $5.00 American now)lol
