Minor part purchase setback. I ordered rear pads for the Explorer that I got the rear end out of, but they aren't correct. The pads are about a 1/2" shorter. After doing some digging on Rock Auto, Summit, Advanced Auto and the EBC site I've determined that my rear calipers' pads and rotors are what came stock on mid 2000's Explorer Sport Trac. I can't tell if the caliper mounting points are the same, but they look close. But the pads and rotors do appear interchangeable with the same caliper bracket. The difference in the caliper is what put me onto it - the Sport Trac has a 'phenolic' piston, or portion of the piston, rather than a normal steel piston. The phenolic Sport Trac caliper piston has a smaller bore in the center where the inner pad clip has to be inserted.
The confirmation was a visit to the part store and comparing the pads and rotors. The Explorer has less brake pad engagement surface area than the Sport Trac. So that's a win - and I'm glad I'm not in any kind of hurry. I have no idea how the Explorer that I got the rear from wound up having the bigger rear brake setup, but.............anything is possible with JY parts.
This issue made me look back through the thread for some info (back into the single digit page numbers). It was enjoyable and a little sad on one note - those that haven't been heard from - lilbowtie - I know his health was poor
But Bruce and Mike's wiseassery still made me smile.
I also probably couldn't have a crush sleeve in my car :/
It was not difficult nor expensive to put in the solid pinion shim. I'd recommend to grab one and be ready to install it the next time you have your diff apart. I measured the crush spacer out of the car and it took about .015" less for the solid spacer.
