I recently bought a used Tremec 6-speed. After getting it home, I noticed a few bolts loose on the tail end of tranny. I removed tail end housing.... lucky me... NO gears on main shaft. Shaft is there.... no gears! I'm looking for the gear cluster for the main shaft (I'm guessing it's the main shaft... it's the shaft that the drive shaft goes to).

CAN ANYONE PLEASE HELP ME WITH NEW OR USED PARTS??????

Thanks, Chad
