Two major choices. 4X4 Parts on Decatuer or if you call and make an appointment Adams Driveshaft in Henderson. Call and ask for John 702-568-5680/1. They do a lot of Jeep work along with other jobs, lift kits, bumpers, re-gear, driveshafts etc.
I have been using Adams for a year and they have a first class product always.
