Are these bolts stock? This is from a wheel I had laying around. I don't know what year or model this is from. I only see 8x33 bolts listed on parts schematic. Has a previous owner drilled through the hub and put these 8x90 bolts in? Is this safe or even stock?

To me those bolts in your pic do not look standard or stock for a CX - too long

There are different lenghts depending on single/dual disc and hub width differs depending on CX/GL type. Keep the sets together.

So I guess have a gl500 front wheel converted to single disc (mine only has one disc)? That would make sense. The threads of the bolts are all screwed up, because of the missing disc. Somebody took the right side disc off and didn't put thick washers on to replace disc thickness. Then the nuts were forced onto the no thread area of the bolts. Now it is all making sense.

Also note that the wheel shown in the parts list picture above is an (early) CX500 Z wheel, single disc with single side short (33mm) bolts in the hub for the disc, no nuts. What you've got is different, 1980+ . Think I've seen one as pictured once here because we always got the double discs, never the single. Make sure you use the correct parts list for your bike/wheel.

(And check the rest of the PO's work, sounds as if he/she/X didn't take safety very seriously, these bolts need to be the correct lenght and installed correctly, meaning clean, correctly torqued and using new self-locking nuts (if present) might be a good idea)

On US Gl's only the interstate model had dual disc brakes

Alos the single disk is larger in diameter than the dual disk setup. what does your disk measure?

I get the same measurement from a naked GL single disk that I had from my son's bike
