I have no problem doing that if it is the most reasonable solution. In my research though I looked up the ignition module for a '81 CJ-7 w/ 258 and an '81 Wagoneer w/ 360, and they are the same part number. The distributor for the '81 Wagoneer has the same hook-ups as the '81 CJ distribtor, and since the 360 block didn't change during that period I figured that the '81 Wagoneer distributor would work in the earlier engine if I plugged it into the '81 ICM. I am a newbie, but the Napa distributor is $70 and the DUI's seem to be about $400, so I'm testing every angle to try to make this work...
