B18 Interchangeable Replacement parts?

Hello All,
Just purchased a B18a out of a 91 teg ls. It is missing the alternator, distributor, fuel rail, and the exhaust manifold.

I was wondering if anyone knows what parts are are interchangable, for instance, can a distributor from a 94 gsr work on this engine?

Or less detailed, for instance, will parts from a b18c work on a b18a. What years are interchangeable, for instance are b18's from 91 the same as in 97?

Are any of the parts interchangable with 88-89 tegs, like the distributor?

Thanks for any help you can offer!
