Interchangability on the cat ???

I know the intake manifold varies from the 90/91 to the 92/93 but how about the cat? I have a 91 and my cat rusted and broke, I found a guy around here with a cat off a 93, will it fit?
Searched the forum, couldnt find the answer anyone know?
It would be much appreciated.

Try a search this has been covered with photos. The cats are 1 & 1/2 inch different between models.
