I am looking for an aftermarket part number for a non locking gas cap (twist on style) to fit a 70 Challenger flip top with CA emissions (Pressure/Vacuum style) Does not need to look original. I think that a 1971 Challenger built before April of 1971 would use the same cap. Thanks.

Year One, part#3194N. Put one on my 73 with slight modification. its non vented and $8.

Thanks, but I am looking for the Pressure/ Vacuum style for N95 ECS.

Google "FC733 gas cap" and see if that does it?

eBay item number:263835368969 as well

Thank you. That would work, but I need a screw on type to fit a Flip Top cover. Thanks again.

Do you have a picture of what your after?

If you look up G806 or 10806, it should look like any of those.

I purchased a couple of these caps on ebay a while back, are they really getting to be this expensive? I certainly didn't pay $60 for one.

If you can't find any elsewhere for a decent price send me a message, I don't believe I'll be using them as our cars have federal / 49 state emissions.

I have been looking at that exact ebay cap for about a week. I just can't pay $60 plus $10 shipping for that. If that cap actually fits like he says it does, then that is the cap I would like. Also how do I tell if I have the April 1971 - 1974 Challenger gas tube? My car is a 1970.

Here's a pic someone here had posted previously, I had saved it for a reference.
