4 bolt swap

[iwantawd]

what would it cost to get the 4 bolt rear put on?
there is a 91 awd with the 6 bolt motor and the 4 bolt rear for 2000 and the rest of the car is stock. why would he do that work and then sell the car?

4 bolt rear's can cost anything from 300-600 just for the actual 4 bolt unit. That's used mind you. Reaon is becaue they're so difficult to come by. As far as installation goes, I'm not sure, I did mine myself. I got my 92 awd parts car for 800, came complete with everything just missing on one, so I got all kinds of parts for cheap as hell.

It probably wasn't stock before.
