Can anyone tell me if the original GM gas caps had the inner ring rivetted or screwed on?? The GM one I got from year one is screwed together, but I have what I believe is a 'real' nos one in the original GM box that is rivetted. If someone has what they know is an all original car to check, I'd appreciate it.

Thanks!

I have a NOS one that's riveted, a original one that's riveted and a repop that's screwed together.
