Help identify BB a/c bracket

[LongwoodC10]

I am looking for help identifying this BB a/c bracket. The motor in the picture is most likely a 402 BB, and it has an Edelbrock intake mounted on it. It is my understanding that the original a/c brackets for the 71'-72' 402's had a bracket that went over the top of the valve cover and attached/bolted to the intake. I am interested in the a/c bracket in the picture, because I also want to run an Edelbrock intake (which means that I can't use the factory brackets).

Anybody have any ideas. Obviously, I don't know a bunch about these trucks, so any help would be greatly appreciated.

Thanks!
