Converting a 63 Dart wagon to 4 speed

ive done a bunch of 4 speed swaps over the years but always on the 67 up vehicles. I’ve got this early clean Dart Wagon that I would like to convert to a V8 and a 4 Speed. Is the 63-66 a bolt in swap or is it more involved than that? I have a later 60’s 4 speed and all the parts but I know the early cars had a 9.5 clutch and bellhousing. I’m changing to an 8 3/4 so I’ll be using the slip yolk, not the ball and grunion.
