This is my last post regarding this axle in this post.
It is a Early Bronco Ford 9" app. 60" wms to wms. 31 spline Moser alloy axle shafts, 4.88 gears, spool, 5 on 4.5 bolt pattern and modified (spring perches/shock mounts) to bolt into a XJ. So as you can see Opie, it's not exactly a stock 9" and yes you did pay too much for a stock full width 9", you can get those for around $100 or less just about anywhere. Good day Sir.
