Hi I am currently gathering parts/guidance for swapping out my powerglide for a th400. I already have a new crossmember (th400), trans mount, and the transmission and torque converter. I don't know what other parts I will need to complete the project. If anyone knows what I need any help would be awesome! Also, I know the pontiac 350 I have takes the B.O.P. bolt pattern (which I got) but will the transmission fit to a chevy mill in the future? (I plan to swap the pontiac 350 for a chevy) Thanks again for your help,
Brad
