Usually I try to buy from American Muscle because they've always done right by me. I'm trying to do a full rebuild on a 2003 Cobra IRS center diff with 4.10 gears. Unfortunately, I've only rebuilt live axles and have no experience on what parts/kits are needed (I'm going to have a shop rebuild it for me). Every time I go on AM to get advise on what parts to get, I get advise that is different than the last or is just complete crap. Can someone on here help me out? What kit(s) at LMR do I need to rebuild the center diff of my IRS and throw 4.10's in there as well?
