The Explorer brake package does have the e-brake expanding shoe inside the brake rotor and I'd like to retain some sort of e-brake.
I'll measure the WMS to frame, inner fender, control arm and coilover mounts tonight when I'm putting it back together.
I haven't bent a retainer yet, but probably only because the bearing is the weaker link and fails first. I think I'll try a set of the A20 bearings and see how they do. It appears that I can get axles and bearings for $300 and they'll fit right into my existing setup.
I'm not sure why I'm just now finding out about this type of bearing setup.
