While you have the manifold out, it may be a good time to gasket-match it. It'll help performance and fuel economy. Manifolds should be interchangeable across any 2.2/2.5 TBI
Your best bet is you local salvage yard. If not there, then maybe some member here has one they can sell you. I'm not one of them, because I don't have any four cylinder Mopars anymore.
Weren't the manifolds updated in the early '90s? I believe the port spacing was the same, so if you can get a later manifold that fits on the motor, that might help with fuel economy and performance slightly.
The EGR tube (or mount) vary between model years, assuming that your engine is even equipped with one. Watch for that difference if applicable.
Example: When I swapped an 88 tall block 2.5 in place of a bad 87 tall block, I had to use the exhaust manifold from the 87. The 88 used a different EGR setup.
