Some of the Fiero panels are easy to mount. You will find you will have to modify the panels to do a neat job; the smc panels are easy. The front and rear bumpers, the front fenders, door panels (if not using the stock door) will not be easy and will be difficult to make look good and to make mounts for. Imsa bodies are easy as they are all fiberglass. What I would do is use the smc panels from the fiero and make replacement panels from aluminum sheet to replace the doors, front fenders, and the panels ahead of the rear wheels. I would purchase fiberglass front and rear bumpers.
