I just did gears in my 1990 Gt AOD, stock with bolt ons. I did not listen to the know it alls on here and went with 3.73's. The 3.73's made a big difference, but I could kick myself in the ass for not listening to these know it alls. If I had to do it again 4.10's would be a must!!!!!
If your going to spend the money only do it once! GO WITH 4.10
I also went with the 373's, which I like...but cant say it was a huge noticable diff...but if I did it again...would prob have to hit the 410's.....the 373's arent as bad on the tac as I first thought it would.
