K Code Bracket
Interesting Mustang Oddity. I’m currently restoring a 1965 Factory GT Mustang Fastback, VIN stamped 5R09C. The VIN stamp indicates it is a 289 2V, but I came across something that I have never seen before. This car has a K-Code style bracket for the rear end snubber bumper, when it should have a standard style bracket instead. This bracket appears to be factory original. This K Code style bracket is flatter than the standard bracket and sits farther forward to accommodate the larger 9″ rear end.

As you can see, the Hi-Po bracket is a lot different from the standard bracket. It has a lower profile. I have only seen these brackets on K-Code Mustangs and Shelby Mustangs. This car might have been a special order with a 9″ rear end. When I received it, the rear end was missing, as were the rear frame rails in the trunk.
This car is very unique because all of the fender apron stamps and title begin with 5R09C. The original door tag is 5R09A, but the consecutive unit numbers match on all of the tags. I found another VIN stamp on the left hand fender apron that was 5R09A and appears to be a Ford stamp. This car also has the reinforcement plates in the rear floor pan under the back seat, which is reinforcement for the GT exhaust hangars. These plates were never used on dealer GT’s and were only used on Factory GT’s. The rocker panels were never drilled for rocker trim. GT’s did not used rocker panel trim mouldings. So, is this car a GT or not a GT? According to Ford, all GT’s should have an “A” code or “K” code. There were not any Factory 6 cylinder or 2V GT’s.
Is this a Mustang oddity since the car should have been VIN stamped with an “A” or a “K” instead of a “C”? Too bad I can’t do a Marti Report on this car (everything earlier than 1966 has insufficient records). If you can shed any light on this, let me know.
