UNFORTUNATELY, IT WILL NOT WORK WITH ANY OF THE CONVERTIBLE FRAMES THAT HAVE THE X-BRACED FRAME, THAT ENCASES THE DRIVE SHAFT. THIS CROSSMEMBER WILL ALSO WORK WITH GM MANUAL TRANSMISSIONS INCLUDING LATER MODEL MUNCIE & SAGINAW, 3 & 4 SPEED MANUAL TRANSMISSIONS AND ALLOWS THE USE OF BELLHOUSINGS THAT DO NOT HAVE THE REAR ENGINE MOUNTS ON THE BOTTOM OF THE BELLHOUSING.

THIS CROSSMEMBER MOVES THE REAR ENGINE/TRANSMISSION MOUNTING LOCATION FROM THE BOTTOM OF THE BELLHOUSING TO THE TAIL HOUSING ON THE TRANSMISSION AND WILL WORK WITH EITHER THE STOCK RUBBER OR URETHANE TAIL HOUSING MOUNTS TO ISOLATE VIBRATIONS. THIS IS NT A UNIVERSAL FIT UNIT. THIS IS A DIRECT BOLT-IN AND ALSO INCREASES EXHAUST PIPE CLEARANCE IN CRITICAL AREAS.
