Thanks, but I know that already I am looking for the width at the flanges. I am unable to measure off of my xj because I am not home and wont be there for a few weeks. I met this guy who has this thing taking up space in his garage and he wants to get rid of it for $150 it has no breaks on it. He does not know what it came off of. Thanks!
The one I am looking it measures 52.5 flange to flange. The axels were not with the dif . he has to dig them up and by the looks of his garage it will take him some time. If I can find this measurment I would know if I could tell him if I want it or not before he has to hunt them down.
