... That's the best you'll ever get...Unless of course you buy a NOS one on ebay which only comes up once in awhile...and for that you'll probably have to sell your left arm for it..
Here's a NOS rear bumper you may want to look into. http://cgi.ebay.com/ebaymotors/1965-1966-Ford-Mustang-Shelby-NOS-Rear-Bumper_W0QQcmdZViewItemQQhashZitem20b073fccdQQitemZ140399344845QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories
OK. I've seen these new reproductions bumpers from Taiwan and I'm not happy with the quality at all. You can see the sand grain marks and also the chrome seems to have "orange peel" to the finish. Of course any of the Mustang houses will say their bumpers are great and I'll be happy, but I don't want to get into a shipping back-n-forth deal trying to find a nice rear bumper.
