Dave by your info the 2579443 is a 66 and I believe is the one i purchased. The 2579442 is really what i need. When i get it I'll see how it sets on the fender. It may be a resale part. Thanks for your help.

Let me know. Because I do not need mine anymore, I sold the car years ago. These are harder to find.
