Just cleaned mine up and gave it a coat of semi gloss black paint. The pic is my Transmission Cross brace and a new (well sorta, bought it a few decades ago) transmission mount. Mine is a Nov 64 Dearborn, Coupe. The only thing I saw (besides some rust and needing new correct, bolts) was a part number, right in the middle. Seems to me, eventually C4 automatics are bound to leak tranny fluid. That fluid can tear up a rubber mount and any paint that may be affected.
