A couple of questions reguarding these: 1. I don't suppose the rear is a high pinion. I was thinking for a swap to my front end of my 80. I found one with 4.10 gears for $200. 2. Could the cable locking mechanism be used on either a front or rear LC diff to eliminate the electronic portion of the electric locker? I know Downey was working on a kit to allow a cable to be used to actuate 80 series diffs when installed in 40s, 55s, 60s; but they don't show it online. I'm one of the unlucky ones as I don't have the factory lockers. I chose vehicle condition and price vs. one with lockers.
