I dont really get your question at all. But I'll break it down as best as I can.

Civics - 92-95 = OBD-1 , 96-98 = OBD-2a, 99-0 = OBD-2b. (The only time the 2a and 2b matter is in ECU harness plugs.)

Integras, I'm not positive about this, but I think...

Integras - 94-96 OBD-1 , 96-98 = OBD-2a , 99-01 = OBD-2b

Now to help you with your question... It doesn't matter what year your distributor is, or what car, ALL B series are compatible, although on the LS and B20 (non vtec distributors) need to have a leg cut off to fit. All you need, for an OBD-1 car, ANY B series OBD-1 distributor, same as OBD-2, for plug-and-play. Also if thats a problem, it is possible to run an OBD-1 distributor with an OBD-2 car (visa versa) by making a distributor "conversion harness."
