Ok, here goes another long winded reply...sorry people.
The Suzuki gearing goes as such, to the best of my memory:
.....snip.....
XL-7
5.125 - auto/od
4.30 - manual

I can scan the document if you would like. It's in my 02 FSB (IIRC).

5.38- 91 8v 5 speed 4 door only

Really? Can I swap 4.62s out of my auto to 5.38s out of a manual? How hard is this to do? Another question is how to find some 5.38s... or which is the easiest gear to find? 5.12s for my 4-door, I think Heather suggested that to me a while back?

pull the axles and remove the 3rd member, put the new member in and reinstall the axles

if the R&P is not installed into the carrier than your best bet is to take it to a shop or someone with experience with setting up your backlash
