Hey guys, early next year, im planning on buying a 69-70 mustang fastback. Right now i drive an 87 coupe with a 308 and the mods listed below, when i get this classic, i want to put this motor in it, untill i can find and rebuild a 351w. So i have a few questions. First off, where would i get parts for a 69-70 model stang, like body parts, suspension, exhaust, stuff like that, second, i have a t-5 in my car now, it could stang being replaced, will a t-5 fit in a 69-70 car, should i get a 4 speed, im torn between the 2, any sugestions? and as for exhaust, i want full lenght headers, but what brand do yall recommend, and what kind of susopension mods are recommended. this will be my first time working on a classic, ive been doing a little research online, but im sure i will have plenty of questions, thanks for the help
