If you have an open inner C, it's as easy as swapping from the knuckles out. Doesn't matter if it's 10 bolt or Dana 44. As for strength, some will argue, but they are pretty much the same strength. The 89-91 might have the edge do to 30 spline axle shafts and not being necked down. Once you get the knuckles off, whats left to rebuild isn't that much. If the axle works fine and doesn't leak, then don't really need to do anything. The inner axle shaft will need to be replaced with a newer one, the splines are the same but uses a different u-joint. Offroaddesign.com has the parts you'll need, whether be shafts or rebuild parts.
