rear rack no bottom eyelets
Any advice for mounting this rear rack? I there are screws up top, but nothing to fasten to below.

Tubus makes an adaptor for QR hubs. You could take that idea and fabricate something. Alternatively, change the upper mount and use P-clamps on the seat stays.

Forgive me for being a newb, but it looks like the QR adapter goes through the middle of the hub. Is that true, and if so, is that hole load-bearing?

P Clamps are cheap, they clamp to the seat stays (or any stays.

The QR system is not load bearing in the shear direction. It's a tension device only. It clamps a hollow, shorter axle to the frame dropouts. The ends of the axle do not extend past the outside of the frame. So you can't use it for a solid axle, but one could fabricate similar adapters. As mentioned above, P-clamps are much easier if you can make the upper hardware work. Often that needs to be modified anyway.

Sorry, I thought you meant the weight of the bike and rider on the hub. Yes, the QR supports the rack weight, but it's a moot point since you don't have QR.

P-clamps are probably the easiest way to deal with this. Make sure you get steel ones; plastic p-clamps are only strong enough for mudguards.
Alternatively, Blackburn used to make "custom eyelets" that fit in the window of the dropout. You can still find them on e.g. eBay.
I'm not fond of mounting racks on the hub axle; it makes wheel removal awkward.

https://www.tubus.com/fileadmin/user...ner_MA_1.0.pdf Here, it looks like the QR system's rod goes through the hub and supports the weight of the rack.
If that bike is unpainted stainless it would be pretty inexpensive to get someone to weld on an tab for a rack mount.

P clamps from the hardware store, they should work with a rack. Wish someone made some bicycle specific ones that looked better. They'd probably sell a lot of them.

Here's what the Blackburn rack adapters look like in real life.
