ok dr diff 30 spline and green bearings it is. theres a lot of info out there and its not always easy to put it all together in a way that made sense.. go easy on me ok :D im just trying to get it running and driving without spending my whole budget. i went with drilling as it seemed like a good idea at the time and would let me keep the brakes. the jig only goes on one way, so im not sure what the deal there was.
anyway thanks for clearing up the axle cosgig!
