I have a 1989 with the G44 and G92 code for the 3.07 rear axle ratio. The car is an automatic. Do I have the D36 or the D44 rear differential? How do I tell which rear end I have? Is there a RPO code for the rear differential? Not planning to change anything, just wondering.


Thanks

Auto = D36

Stick = D44

RollaMo-LT4

Except for the 1984 models, which were all D36

This also assumes a previous owner hasn't made a rear end swap.

Best way to tell is to crawl under there and look.

Thanks everyone. I'll have a look see RollaMo using the picture.

You can look up pics of D36 and D44 on the net. You will know right way which you have.
