Gas Cap

[zrone90]

Is there a special gas cap for the retractable. Every website I went on to purchase one said not for retractable and station wagon. I assume it is vented cap. If it is a special cap any Idea where I could get one.............Thanks

I've never had a problem finding one, the last one I got was from Car Quest # 34013, I also saw some on e-bay but different brands.
