This is a pair of original sunvisor brackets. They are in good driver quality condition. The swivels both turn as they should. The tightening screws work fine. They have not been overtightened. 

The chrome is very shiny, there is light pitting if you look closely. One is better than the other, neither are bad in my opinion. 

Both brackets have casting # 5716816 on the underside.

These should fit many 60's GMs. Please check to make sure they are right for your vehicle. 

I would like $20.00 plus actual postage for the pair.
