While a late 6 won't bolt to an early bell housing, a later bell housing will bolt to an early transmission, making this a easier update than sometimes thought. I've done it. I don't remember for sure but it seems to me I used a bell housing from a 3-speed car. I am sure it was a 1/2 ton truck with a 3-speed in it also. Its been a while since I done it and I'm sure I done it but don't remember exactly the parts involved. I didn't plan it, it just happened the parts on hand worked. 1 OL REDNECK
