Replacement gas cap for 1967 window van

I finally did the inevitable and drove off from the gas station with my gas cap on the roof.

I picked up a locking cap, but it doesn't really fit well.

I've been looking at few different styles to replace my replacement, but thought I'd throw out a net for some style [model #'s?] suggestions from someone that can testify to the fit.

Will a Falcon gas cap fit the neck on these vans/trucks?

1967 e100 window van w/ 'Falcon' trim.

you can't leave this on the roof... http://www.ebay.com/itm/Mopar-FLIP-TOP-GAS-CAP-69-70-Charger-69-Cuda-NEW-/370609808011?pt=Vintage_Car_Truck_Parts_Accessories&hash=item564a10e28b&vxp=mtr

That flip-top is nice.

Anyone else have any aftermarket suggestions that they have personally seen fit?

That or a correct part# for a stock replacement?

Thanks!

I use a aftermarket 75-77 garnada cap From stant 10735.They have it on ebay
for around $13.00.Carquest #34036 It fills the body cavity nicely its 4"dia.

This is what I got for an econo. The part number crosses back to earlies on other sites and this works great on mine and is stainless.

Thanks for the replies guys. you're both finding that these caps are fitting snug?

That's a big help, I appreciate it.

Yeah. Mine fits nice and snug

I like about this cap it snugs up real nice.Good grip to twist on and it
fills in the gap in that area.I`ve also filled in one, in the middle with
filler and painted it to match the body color.

thanks for the testimonials guys. I ordered one of the ones Stunami suggested, but I'll probably grab one of zbermen's too for a backup

anyone else had any luck with a locking cap?

just a follow-up.

I got one of the caps that Stunami pointed to: http://shop.vintageford-streetrod.com/1949-59-Pass-1951-70-Pickup-Gas-Cap-8A-9030.htm
and it totally fit snug as a bug.

Visually, it is a little small, you can see the filler neck mounting screws behind the cap, but I swung by Home Depot and got some stainless #8 1/2 inch screws and it's clean enough for me. I'll post pics when I get a chance.

Glue a econo horn button on it. I read here somewhere that's what some people were doing to old horn buttons. I think it would then hide the screws.
