1 spring, no white ring.

The little coil spring and button contact are part of what allows many GM wheels to interchange. The nut is the main steering wheel nut.

If it is now working, best to stop fixing it. But save any parts removed.

Thanks!
Yep, I'm not touching it in now, works just fine

I'm guessing maybe original owner bought a replacement kit of parts, put both the new and old spring in, maybe the plastic piece is for a different model or something but everyone was solid and wouldn't press down with the plastic piece in there

It's in a show box full of other misc stuff from the truck
