Nice buy, i ended up giving my stock rears away once i changed to yfz rear hubs. My swinger is messed up as well, i've been on the lookout for an aftermarket of some kind but havent pulled anything up yet. I figure I'll either have one made if not do it myself. I am curious how do the 85/86 motors run? Mine never ran right, and instead of rebuilding it im putting in a 90 motor. I still have a bunch of motor parts from the old motor if you need anything.
