Advice needed on how to fix a couple issues with my new SDA SRS

I picked up a set of SDA 2B Studios a few weeks ago, and successfully spiked them and replaced the SL2000s with the RDO-194s. I've been enjoying them immensely.
Then, out of the blue, a set of original SDA SRS (blade-blade) became available near me. Now, I had no intention of ever owning a set of these because they're far too large for my listening space, but I have to admit I was curious and always wanted to hear them. Why not spend all my hard earned cash and use up all my goodwill with my friends by asking them to help me haul a couple of refrigerator-sized monsters into my basement just so I can hear what they sound like?? So of course I went for it.
I bought them from a grandma who used them only with a karaoke machine. Seriously.
Anyway, they’re in nice shape overall. All the drivers work, they sound fantastic (although a little overbearing in my little space), the grilles are mint and they just have a little ding or two on one side. I just did my usual Howard’s Restore-a-Finish and Feed-N-Wax treatment to the walnut and they sparkle. But I have two issues I still need to resolve to get these babies back to their former glory:
1. 2 of the woofer dust caps are pushed in. I’ve solved this before by putting tape on them and pulling it off quickly, but the SDA drivers seem to have a stiffer cap and this method doesn’t work. Anyone successfully pulled a dust cap on these before?
2. The top left binding post on the speaker connection plate of one of the speakers has broken off the plate. So there is a quarter sized hole in the plate and the binding post is still making a solid connection to all the wiring but it’s just hanging there. Does Polk sell replacement plates or is there another solution that might fix it? I was thinking I could put a fender washer behind the plate and another one on top to complete a solid connection. But then I’d need to seal around it with silicone or something. I don’t know. Seems kind of shoddy. These speakers deserve better. I’d like to do everything right with these.
Any advice would be appreciated. Thanks!
Oh, and before anyone asks, I’m running them with a Sony STA-7065A receiver as a preamp into a Crown XLS 1500 (525 wpc at 4 ohm).

to fix the dust caps it takes two people...1person to turn on the vacuum and right back off that quick, the second person is holding the vac tube on the dust cap the other hand holds the woofer in a little and makes sure it does not get pulled out off the voice coil. DO NOT LET THE VACUUM PULL THE WOOFER OUT
second problem need a new binding post plate sounds like. with a hole that big it will affect the bass real good in those...do not use silicone hot melt glue would be better. Silicone off gasses acetic acid gas no good for wire....
others have used a tube the right size of the dust cap PVC, paper towel etc. to place over and inhale to pull cap out....I have had no luck but I would try first to see it your luck is different.. -
Good stuff, thanks. I'll try both tonight, starting with the tube. I'd read about that somewhere a while ago and forgot that was an option.
Maybe I'll put a WTB ad out on the plate. I know people upgrade to aluminum plates and better binding posts. Gotta be some old ones lying around somebody's parts bin.
