I've toyed with other ideas (retaining the Wilwood calipers, fabbing up brackets, getting rid of all the aluminum bracket/backing-plate/drum brake arrangement, and finding another parking brake solution (little mechanical calipers with small puck-like pads). I have a feeling starting from scratch might be easier. By the way, does anyone make a sort of spanner wrench for the bearing adjustment?

It isn't much but I'm pretty sure that the rotor center is slightly thicker than the drum center. If I had both parts laying here I could measure it for you but I don't have the parts on hand at the moment.

If it is that small amount (and going to make a difference), you could always have the mounting pads of the wheels cut that much to even things back up. Usually enough meat on them to skim some off if needed.

The Bear calipers have a smaller piston area than OE MOPAR so you need plenty of brake pressure. If using PB the 9" booster is marginal. A twin 8" or hydroboost is better. Getting front rear bias dialed in requires a prop valve and even better, smaller wheel cyinders on the rear + prop valve.
