G80 = Limited Slip Differential (posi)
G92 was used for a few different things over the years but most of the time GM used it for gear ratios of 3.08
You should have a RPO code for the specific ratio.

3.45 ratio = GM3
3.08 ratio = GU4
3.42 ratio = GU6
3.27 ratio = GW6
Limited Slip = G80
Performance ratio code = G92
3.08 ratio = GU4
3.42 ratio = GU6
3.27 ratio = GW6
Limited Slip = G80
Performance ratio code = G92
