radiator replacement

ok guys i know its easy to replace a radiator but i'm questioning if i should blow the $$ on one. Also how do i know if my motor has the oil cooler or not because thats a big difference in $$ when buying a radiator. See the problem i'm having is the plastic fittings on either side of the radiator are leaking. I have a feeling it may be from a wreck my sis had a few months ago. Now do i have replace the whole damn thing or is there are better way? I'm open to suggestions.

92 PA Ultra

I have a PA without the transmission oil cooler from the factory, I installed it myself though. The radiators are the same, the only difference is the trans fluid lines are different. The trans cooler sits in front of the radiator on the pass side.

so its the little one that looks like a small radiator in front of the radiator near the passenger headlight?

Right. It should have horizontal fins, with it's feed and return line going through near the passenger headlight.
