Well I got the spring perches moved to where they are susposed to go. It wasn't too bad. I am going to be removing the 7.5 out of the BII this week while I wait on a new alternator (mine died and Summit is replacing it) and the new u-bolts/springs plates.
Here is a couple pictures from today. It is amazing that an Explorer rear axle is the same width from backing plate to backing plate as my BII.
