You may already be aware, but there's a salvage yard in Denton, Texas that has several versions of the cars/years You are talking about. They specialize in old cars. They may be able to help you find what you are needing. It's CTC Auto ranch. Again Denton, TX. Their website has pictures of most of the parts cars they have. The stuff isn't going to be free but still worth a shot if you can't find what you're looking for locally. Good luck
