I have the XJ 30 at the front and the JK 44 rear. I added a 2" spacer/adaptor both sides of the XJ 30 and fitted with JK take off wheels. One cannot tell the difference by looking at it.
Are you close to Memphis? I have a D44 front in Olive Branch MS that I need re-gear. I know where I can get it done in Florida but not in Memphis or the surrounding areas.
