i have a t-5 that is completely trashed. my 85 z-28 was originally an auto. i want to convert to a th 350. it has aholley 4 bbl and a 350 crate motor with no computer controlled anything. if i get a 700r4 tailshaft conversion kit for a th350 will i need anything else to mount the transmission? where can i get the kit? does the th350 need the computer?
