I have a centered AMC20 from a 1980-83 Wagoneer/1984-86 Grand Wagoneer (fits other years as well) for sale. It currently has 3.31s and an open differential in it, but I have 4.10s and a Trac-Lok limited slip ready to be installed. I can do the work. I decided to go a different direction for my project. I have new pinion seal to be installed as well. It's just under 59" wide with the 6 on 5.5" bolt pattern. Stock spring pads and shock mounts still.
