Will it fit?

So I have found a 4sp tranny, from a 68 roadrunner, short tail, no bell housing. Owner says he has a bell housing available, no additional info. I want to mate this to a 1987 318 block to install into a 1975 Duster. Is there any way to determine if 1.) the tranny is good, 2.) the "available" bell housing will mate to both the tranny and the 318? thanks in advance.
