Im alittle confused. The shifter brezel should not be affected by the tranny being a little higher. It snap into place on your center plastic consol.
I run prothane tranny mount dont seem to have a problem. They dont make different hieghts, they only sell one for the foxbody stang. I have run the same mount on my t5 before switching to the TKO500.
I have however run in to a height difference on the prothane motor mounts they do make the motor sit about a half to a inch higher.
