DID NOT FIT MY TRUCK
I ordered this cap while my truck was in the paint shop. The paint shop took a lot longer to paint my truck than expected. By the time I got my truck back from the shop, the return window for the gas cap had expired. This is my fault, not the companies. I just want people to know that the cap will not fit a 1975 Ford F150 as stated.

They fit.
What else is there to say?

Meh....
These are not shiny at all. They are more like a stainless steel look and have ZERO shine the old ones I'm replacing. The picture in the ad is NOT what you get.These have been thrown on a shelf and that's where they will stay until I can give them away. There's no way I put these on my classic ride. They don't even begin to resemble the chrome on my vehicle.

Not bad for the price.
Nicely made and mostly fits what I got it for (a 1958 model car restoration) but the retention ears are a little short and it can be turned past the lock position.

Sure does keep the gas in the tank
It's a vented gas cap that fits my Bronco. Not much else to say.
