A: I have an '86 XJ M15 (I think it still says that on the webs) with trac-loc. ( I got it for $100 with 3.55 gears) Subject: AMC 15 ear ends To: mail@xxxxxxxxxxxx Someone mentioned posi 15s in AMCs and they were indeed available. I have one in my 65 440 as the last time I played with it I left two 235-60 patches behind. I had installed the large brakes back there so I don't have those cute little American binders anymore. I pulled a posi 15 out of a Gremlin at a boneyard once too, so they came in many forms. I believe the Jeeps have them in quite a few rigs. If shopping, just yank off the plate to check as you can't rely on turning the wheel. The posi unit could be damged or froze and not allow both wheels to lock, so pull off the plate and look around. Just remember to replace with two bolts to protect from the elements......Russ
