        So on these caps do you just screw off the old caps, screw on the new caps? What is the deal with the reviews I read about trying to get a pin in, and issues with that? 1 answer
        When this oil cap first came out, there were reviews that said the rubber o-ring that the cap comes with wasn't right and that oil seeped out. They ended up taking the o-ring from the stock cap and using it on this one. Does anyone if that issue has been corrected? I'm about to install this and don't want oil on my custom valve covers. Thank you. 1 answer

            Doesn’t fit, so sad

            I was really hoping to complete the look with this oil cap but it’s just slightly too big even though it says it will fit. It doesn’t do at this point it was a waste of money on the whole set, I like all the other caps though so I will keep the set but should have bough individual

            Mine might have a loose fit its falling off twice now. Thought it odd I was smelling burnt oil I pull over and the cap is resting off the valve cover oil is on the bottom of the hood, on my fuse block all over the inner fender well I lost about 3 quarts outta 8 of royal purple and when your oil cost 100$ each oil change and this has happened twice, this 39$ cap has almost cost me an oil change by falling off twice. I'll be putting the stock locking one back on.

            BILLET radiator cap cover 05-10

            I accidentally ordered the radiator cap cover for the 05-10 instead of the 86-04. When I realized that I looked it up and A.M. says that it won't fit my car. WRONG!! It fit perfectly! MAYBE SOMEONE FROM THE A.M. STAFF WILL READ THIS AND MAKE SOME CORRECTIONS. thanks AM. Took all of 10 minutes to install. Looks great!

            Underhood dress up kit

            This modern Billet chrome Under Hood dress up kit is a must for those who show their cars. As a matter of fact I received it two day before a show ,put on and took first place in 1976 to present. There were approximately 30 mustangs in that category including two GT 500’s and a Bullitt.
