I have a 80' el camino with a vortec 350 bored .30 over. i put a Th400 in it and i'm about ready to button up the ride but I'm worried about what kind of drive shaft i need for it. The transmission is out of a chevy pick up with the fixed yolk on it. I'm wondering if i can just put a slip yolk on and be done with it or do i need to stay with the fixed yolk. don't know if the slip yolk will ruin the bushings and what not????
