Let it sit overnight clamped...at first it seemed to work very well...
Until it didn't...
When I test fit the retainer over the T bolts, the spacer ring popped loose when it snapped into the axle end.
I've got a couple of different options here now...I can glue it again and hope it stays in place until I get everything lined up and start tightening down the nuts on the T bolts, drawing the spacer ring inside the hole in the caliper bracket...
Or, I can glamp it back together again and put a couple of spot welds on the inside edge of the ring and retainer and hope that holds better...
My last option is to have my friend John build me a new set of retainer plates with the spacer ring built into them...but that ain't happening this weekend.
