I had a 3.07 in my '04 TJ (62,000 mi) and I wanted to have a 3.73, but it didn't seem economically feasible. Just traded for an '06 TJ with a
3.73 rear. Problem solved :-) It has the 25X package (Ecco aluminum wheels, 3.73 with Trac-Lok, Hard top, A/C, cruise control and 6 CD changer) And the previous owner was thoughtful enough to put on BFG T/A's 31x10.5 R 15 tires. Only has 23,000 mi. :-) Silver with a black top and a very nice after market tube front bumper. Not new, but close enough for my budget :-)
