New to the site. Just got a 2005 Silverado Base Work truck. Has the 4.3L 6. I can't seem to find a locking gas cap. Done multiple web searches on various auto parts places. No luck. Anybody able to help? With the price of gas as it is, need some way to lock up. Thanks.

 

do you have advance auto parts where you live? also, if they have a locking cap for a similar chevy truck, or different chevy product, check to see if they are the same.
