Need a new gas cap-old one was locking type with no keys! - I think it should be a non-vented cap. Where can I buy a cap like that that looks original?

one of these?

I bought one for our '69 el Camino from our local GM dealer about four years ago. It pays to check with them first.....if they have a good parts guy who is willing to look in the old parts books.

Check Rock Auto. They list two different depths for the cam. The cap should be non vented. I had to buy the deeper cam cap to fit the tank I bought from them. My original cap was the shallow one but the rubber on it was trash anyway.
