Where can I find replacement parts

What is your question?

I am looking for a chrome plated plastic speaker Bezel which would be for the driver side door speaker. The only identifying markings I've found are 84342 with the 2 being a guess due to the fact that is was a badly casted part in the area. The rest of the markings are >ABS< L1. If anyone can help me it would be surely appreciated. Thanx drew6126@yahoo.com (248-660-3868)
