I am having a really rediculous problem. I cant find the right locking gas cap for my 98 camaro z28. Alot of kids live around me and I am trying to take precaution before something winds up in my gas tank. I have bought 4 different caps now and none are correct. I even went to napa auto parts. Do any of you guys know where I can get one.I know stant makes these caps.If you know the part number that would be great. Thanks for any help u can give.
