96 bonneville parts hard to find

My husband bought me a 96 Bonneville SE for 800 that had sat for a few years. After replacing injectors, three sensors, fuel pump, and fixing a vacuum leak it run like a new car. The body and paint are great. but it has a few minor problems on the inside. finding a car with the parts I is a problem. The seats are black leather and the front bucket seats are fine but the back seat is in bad shape. I also want to raise the factory wing a inch to stop things from getting stuck under it but don't no if it can be done or if it should be done. After I do all this the last thing on my list is to replace the bulbs in the fog lamps. call me weird but I'm saving the simplest thing for last.:evillol:
