Assuming you can shoehorn it into the available space, which is only a matter of checking sizes, you'll probably need to add/remove/make some new mounting brackets.
The main issue I can see is having to make up (or get made up) lines to connect the original fiero ac coindenser connectors to whatever size and wherever they are on the new condenser. Also hope the placement of the connectors on the new condenser is not blocked by anything on the car making connection difficult or worse. By the time you've finished, you could be in the same ball park as that $235 condenser.
But good luck to you if you decide to go that route.

Anything I might say is probably worth what you paid for it, so treat it accordingly!
