Manual brake bracket from 79-80 F-body or maybe Diplomat

Looking for a manual brake firewall bracket, should be found on 79-80 F-body or maybe an early Diplomat or similar. Could be part # 3766120?

At any rate, it looks like the below, and yes the pics are stolen from aspenandvolare.com, obviously I don't have one to take a photo of.

Thanks to badvert65 on aspenandvolare.com for the pics and to 80aspen, NoCar340, slant6billy and High Speed Pursuit on FMJ for the info.

I know a lot of you have non-A-body parts cars lying around, so... thought I might have some luck here on FABO!

Thanks.
