Any hope for my old ME E-11?

Some good news for ya', Dave... E-11s are not a requirement for basic approval, only for EI and above. (See bottom of this post). Besides the wire/item on the side it is connected to, the charging handle, end cap itself and perhaps the bolt opening you are actually in pretty good overall shape for level 2!

Resin builds have come quite a long way, and there are replacement parts available that can be 3D printed. Don't worry if you don't actually have a 3D printer, though, there are services online that can to it inexpensively, and many folks here offer the files for free, like this:

You can also have them made in cast aluminum, but those are pricier: (I used this eBay seller to replace a ton of parts on my resin build).

I hope this helps, and here is a thread that should give you some more details/guidance:
