If the diff cover is round, like a perfect circle, It's an AMC 20. If there are nuts on the end of the axles, at each wheel, (under a little hub cap usually), it's an AMC 20. That's what came stock in 85 though it's not unusual for people to replace the stock axle/hub assemblies with one piece axles like most semi floating axles have, in which case there will be no nuts on the axle ends). The Key thing is the round cover. <img src="/forums/images/graemlins/cheers.gif" alt="" />
