RE: diff problems

you will have to check your rpo codes for your gear ratio. They should be in your glove box.

GU4=3.08
GU5=3.23
GU6=3.42
GT4=3.73
GT5=4.10
HC4=4.56

So long as it has the same gear ratio as your current rear end, it should be a direct swap.

RE: diff problems

If you have verified that both carriers are equivalent (ie. that the other one will fit), then you can swap the gears onto the replacement diff and then go through the proper setup of your diff.
