Ask and you shall recieve! (Flip Top Gas cap Adapter)
Any serious differences that will give me trouble will be how deep the recess is around the filler neck. Chrysler was pretty good about keeping thing standard, but really that's something that can different and not be noticed without measuring it.
As far as price goes, they are 31.00 on here only. If you go to Ebag, then it may get quite a bit higher. However I havent had a lot of them lately.
By the way, price wise, you cant get much cheaper on these. When I first started these, I gave the pattern to a few select people because I had no intention of making them. Those people had them made and paid more to have them done. The material and cost to have it machined is NOT cheap, so..... Believe me you are getting a good price. Not to mention I have had people pay quite a bit more on ebay.
Thx for your interest guys!!
