I have been running repro brackets on my 1932 for 22+ years with no problems.

I did relieve the inside of the clamp brackets (facing the glass) with a die grinder for a cavity for the rubber pad to extrude into when tightened, this helps prevent slippage of the pad. (Similar to the original clamp brackets which were relieved and the pads had a matching bump).

I also was very careful to adjust the clamp so that the clamping force is even front to back... I had troubleshot a number of glass falling out issues and looking at the pads it seemed that most had pressure only at the front or back, leading to failure.
