Third gen to fourth gen gear swap

I have a 1990 trans am GTA with 373 gears. Anyone know if the gears would fit my fourth gen TA? From what I understand they are both 7.5 inch rear. But I want to see if anyone has done that

'assuming' both are 3series,both the gearset from the 1990 and the carrier in the 2002,should be a typical swap.

Thanks. Yeah my 90 originally is a 323 geared car. So I believe it's a 3 series carrier.
