The 7.5" rearend in my '84 just died, so I pulled the 8.8" rear out from under my '87 donor wreck. I ran the door tag on the car through the decoder on the GT Registry site and determined that the car came originally with 2.73 gears. (YUCK!) I pulled the cover and found the code stamped into the ring gear. My question is, are these the original gears? I noticed that the cover was sealed with only black silicone, no gasket. The code is:
