Just gave my beat up Monitor 7b's some much needed attention. Along with all the normal mods I also replaced the vinyl wrap with veneer, rebuilt the crossovers, and installed some front to back cabinet bracing. Everything was going smoothly and then this happened! Seriously!?
I guess in my attempt to make sure everything was sealed as tight as possible, I over torqued the screws. Definitely won't seal properly with that piece broken out. The plastic is 40 years old too, but obviously it was my fault.
I made a couple of plates out of 16 gauge steel as a temporary fix while I try to find a replacement, but they might just stay though. They look decent and are definitely functional. Plus who looks at the back of a speaker anyway?

Hurricane nuts and threaded bolts, torque them down and your cabinet will also stiffen/strengthen there.Don't take experimental gene therapies from known eugenicists.

I have an original 7B binding post plate you can have. You will need to transfer your fuse holder though as it was removed from mine. Send me your info via PM if you want it.

Don't feel bad, not your fault. Mine (1980) had disintegrated around most of the screw holes without being touched. I replaced mine with custom fabricated aluminum discs and Cardas posts.

I had the same issue about 4 weeks ago on one of my 7Bs. My fix was my son 3d printed out a black "ring" about 0.09" thick and I used jbweld to epoxy the ring to the plate inside surface. Drilled out for screws, then screwed the plate on at the broken areas with longer screws and a large flat washer to capture the remaining plastic. Seems to work well for me, at some point I will look to replace the plate as well.

Does this imply we are ALL getting OLD?"Sometimes you have to look to the past to understand where you are going in the future"Anger is just anger. It isn’t good. It isn’t bad. It just is. What you do with it is what matters.
