tranny question

ok i went up to the shop and took another look see the tranny and converter off the 318 is a lock up 904 and the tranny that i am using is a 904 non lockup! so eithor im gonna have to buy a converter or fix the tranny off the 318 i was wrong about the lenght the slant 6 and 360 are the same lenght the 360 had a plate on the tail shaft that makes it appear longer but its not!
