This equalizer bracket was attached to my donor S code engine when I bought it in the late 80's. The donor engine is a "322" (M/T), dated 7M. I do not know what vehicle the engine was originally from (Mustang, Cougar, Fairlane), and it may have been installed in an entirely different vehicle before it made its way to me. I haven't been able to find a match for this bracket in any online searches, and there is no part number. It may even be an aftermarket bracket for all I know. I'd like to ID it in order to sell it - my project has a C6.
