After getting another set of brackets for the rear brakes, putting them on, and finding they didn't fit I was getting tired of the rear brakes. (That set was identical to the old ones that didn't fit.) Finally, November 24 I got the newly redesigned set of brackets. I put them on the next day and there was some space between the caliper and the wheel. It wasn't a lot of space but enough and I'll take it.
Here is a comparison of the new and old brackets. The new one has a rounded edge as it goes around the bolt hole. (In Wilwood's parlance, it is fully "radiused".) The old one has a flat cuttoff as it gets to the bottom edge around the bolt hole. In the below photo the bottom one marked PS is the old bracket.
Lastly, there is a new code stamped into the redesigned bracket, 12364 LBB.
I also put some more dynamat inside the passenger footbox and in the transmission tunnel. I love how solid that stuff makes the car feel. Oh and I found a wire nut in the driver's fuse box area that I replaced with a soldered connection. Wire nuts = bad choice for this application.
