I have a Globetrotters machine I am playfield swapping (my first), and I'm trying to locate a replacement for the little brackets under the Thumpers (similar to the one shown here with nuts affixed). I can't seem to find them, and am unsure what they're called. Didn't see them in the Bally parts manuals. Are they still something that can be found for purchase? Or is there a modern replacement part? Otherwise, it'd be pretty straightforward to make a replacement bracket and just use washer/nuts. Thanks!
