Re: M20/trash-lock question
2.73s have their own carrier. Your best bet would be to get an open carrier and put a Lock Right in it. I have spoken against a Lock Right in the rear, but with 31s and it being your wife's vehicle it will probably be OK. The factory CJ Trak Lock is set up wimpy, it is pretty useless. No other springs are available, and I've tried shimming, jsut won't work on the Jeep Track Lock, unlike the Ford version.
