Well, I made my decision on how to do it. Theres no going back now

The only real decision left is how far apart to drill & tap the two caliper holes...
Bill, The calipers will still be a minor pain to remove. The VCI adapter taps the caliper body and the bolts come up from the bottom - not down from the top like the fronts. There really isn't room to counterbore a hole from the top (the bridge bolts kinda get in the way.) I'm planning on the same way.
