You might want to see if AMD offers your bumpers. I got new bumpers for my 70 Dart GT and they are the nicest that I have ever had, even though I have 3 70 Darts, and for a lot less than $800
It better be a special car to pay those prices for a Bumper on an A-body. Otherwise I would be embarrassed signing my name on that purchase..... Hobby needs an enema...
