I rescued my first vehicle and first Comanche a couple months ago, picked it up for $800 and brought it home. Only other offers the previous owner got were for the bed and nothing else. I was the only person who wanted the whole thing. It was mostly torn down with the motor and transmission missing, but luckily we have a 91 XJ sitting around that I've been robbing parts off of. The XJ is in rough shape body wise, but in good mechanical shape.
The comanche isn't perfect by any means, no... It has literally no options except the sliding window (the seats are out of a 2 door XJ and aren't original) The floors and frame need love and the windshield is destroyed, but it's a fixer upper.
I've already got a bunch of stuff fixed, and put the 4.0 from the XJ into the truck. I need to do a lot of harness work to mate up the 91 harness to the 88 connectors, but it seems like all I need to modify is the rear harness, as I'm swapping all the front electrical stuff from the XJ in, including the AC from it.
I have a big list of parts I'm gonna get eventually and I still need to get a driveshaft and fuel lines to actually run the truck, but everything I have found so far works.
