Ok! I was able to track down two new backing plates, just like my originals. If all goes well in couple days, when I install the new ones, I’ll give the old ones to anyone on here to try to refurbish, if anyone wants. They’re a little rough, but I think they can be made pretty good, still. Maybe someone on here has a machine to do it in. I don’t.
I’m in Connecticut. You either have to pick them up or pay for shipping.
