Re: rear end question...
A 10 Bolt carrier (7.6") from a 1990-2002 axle will not fit in a 9 bolt Borg Warner axle. The BW would need to be swap out with a 1990-1992 28 spline GM 10 bolt.
This link is about brakes, but midway done, there is more info about the 9 bolt BW and 10 bolt GM axles.

Hope this helps.

Re: rear end question...
The only thing similar between a 10 bolt and a 9 bolt is the mounting hardware how they attach to the car. You might as well be trying to install a 28 spline carrier from a Ford 9". It just won't fit.
