Hi Joe, I realize they were factory matched. I have spoken to a couple differential specialists and they said the same thing. However, sometimes you can get them pretty close with donor caps. If I have to remove the axle tubes to have the center section machined, I'll cross that bridge and consider the economics at that point.
