72 dart Transmission mount?

Can someone reccomend a transmission mount for a 72 dart? I bought one from oriellys and it was taller by about 3/8 or better. I figured my old one was compressed a lot (even though it didnt look it) so now I hear some harmonic noises from the engine and would assume the transmission is pushed up too high. Does anyone know of good mount that's closer to specs I could replace this one with?
