Interesting on the rods. Did the 3 games come from a common location/arcade/etc? I wonder if someone could have just done some mod to multiple machines. The fact that you have 3 is curious, as it either means one person put them on multiple machines, or they somehow came from the factory that way. If you know any more about the history of the cabs, I'd be interested to know.
One tip with the roll pins - When you install them, put them in so the rounded part faces down (i.e., the slot faces up), so the rounded part rubs against the sides and bottom of the slot in the case. If you put the slotted side down, it'll be sharper and wear against the case faster.
Also, use some 100% silicone lube when you reassemble. You can get it at any auto parts store for like 8 bucks, and it works better than anything else I've tried on these sticks (and any other stick that uses lube). It's sticky and stays where you put it, and you don't need to use very much, as it's very slick, and doesn't dry out.
As for the bezels, your best bet is to repair and save the ones you have. They aren't easy to come by, especially unbroken ones. I've repaired them by JB-Welding the broken legs back on (and you can be missing one leg and they'll still work ok). And you don't need to tighten them super hard when securing them, as that will crack them again.
The metal ones are expensive, but they are the best way to go, as any plastic ones are likely to break eventually. The plastic for the bezels and stick bases is brittle, and has gotten more so over 35+ years.
