I got the driver's side done this morning. I decided to take it all apart and reassemble it with NO spacers to see just exactly what the clearance issue was. Finally having time to really look it over helped me figure out the best solution. I got the Dremel out and was able to remove a small amount of material to get enough clearance (about 1/16" that I was looking for with the spacer). The abutment bracket ended up being thick enough that I don't think this will cause any issues. I was able to completely reassemble the driver's side with the new parts finally (including new braided brake lines).

I got the passenger side apart and was able to see I have even less clearance on that side. Hopefully I can finish it up later since I'm tied up on something else this afternoon.

Thanks for all the suggestions!
