8.8 rear, open diff. No tag on rear, I haven't gotten around to figuring out the ratio. Drum brakes, original leaf spring mounts. I believe this is out of a Ranger or Explorer, measures approx 58" wheel mounting surface to wheel mounting surface. Brake parts were in pretty good shape last time I checked (a while ago). Recent black paint job, not at all dirty and grungy. $100 takes it!
