Sorry I have not responded until now, I have been takeing care of two dogs the we had fixed. Anyway I have already installed rear diff from a 2000 Explorer, the disc brakes makes a world of difference. I just ordered some 4.88 for the front diff today. For right now I am going to cut down the axles. but plan on upgrading to chrome molys when I can afford them. I plan on installing a E locker on the front also when I can get some $$$$.
