What is the correct gas cap for a 57 imperial? I am open to locking and non locking style. Almost prefer a locking type now days but will settle for a regular stock replacement.

Thanks!

The 57-59 Imperial has a unique, tiny gas cap. Good luck fitting a locking cap in the hole
Originals are outrageously priced if they can be found at all.
Search eBay for "john deere pony gas cap"
This is one of the first listings to show up https://www.ebay.com/itm/173919485832
It's virtually identical to the factory 57-59 Imperial cap except for the finger tabs on top

Autozone has this one as compatible https://www.autozone.com/fuel-delivery/fuel-cap/duralast-fuel-cap-60... but I have ordered 2 in the past off ebay that say compatible and they arent so asking here.

Would the one listed by autozone fit? They give some dimensions of the filler neck 1.354 inches which I can't verify until the weekend. I may order that tractor cap, thanks for posting that KcImpeial

Here are some pics of mine. looks like a Stant but not sure. Dimensions are in mm. I note that ther's a little play but the cap stays locked.

[edit] looks like xo-1908 is for a 67-68 Camaro ... But also others Mopar https://www.ebay.com/itm/57-58-59-60-61-62-63-64-Dodge-New-Locking-G... (but i didn't pay 150 $ ...)

Ok but you'll have decimal inches and not fractionnal !
33 mm = 1,29921 "
34,8 mm = 1,370079 "
That what my calipers will display

I've found this https://www.rapidtables.com/convert/length/mm-to-inch.html
so 33 mm = 1 19/64 and 34,8 mm = 1 3/8
Magic !!!

Yeah locking one from auto zone duralast 5092 is 1.36 inches. It does not fit in the neck. Im guessing the one you have Phil barely clears the neck to go in?
