First, very frustrated and yes I did use the search before posting this. After learning the hard way that I needed the rear out of a 4x4 and not a 2wd I now have both. Problem- the one that fits needs seals. Figured I would replace all the bearings while I was at it. Obstacle-the bolt that holds the center pin broke on disassembly. Can I just drill it out and use the diff out of the narrower one and put it all together. 4x4 is an 83 and the 2wd is a 94. I'm guessing from what I've read that the spline count is the same and it should swap. Thanks ahead for any input. Gonna walk away from it for a day or two so my blood pressure will drop.
