If you don't find one and can wait a couple of weeks, I should have one you can borrow. Dunno if it matters, but mine's a '94.

FYI 90-93 cat is different than 94-97 and NB is welded into mid-pipe.

You might want to diagnose the problem before putting on another cat. A bad O2 will foul a cat pretty quickly. Pull any engine codes and let us know your emissions readings. That might help diagnose the problem.
