Yep, the washers don't touch -- so no problems there. I can tighten the brake on there in the correct alignment and then literally take my hand and pull hard enough in the direction that braking would deflect the pads, making the whole brake move out of line.......yep, poor design for the rear bridge. I'm going to try the lapping compound job since that will allow me to theoretically use the brake I already have on there. If for whatever reason that doesn't work, I'll move to the other options.

Thank you very much for the help!
