Here's pics of two different gas caps.
Both are listed at eBay and sellers are stating that their cap will fit to a '70 Challenger under the flip top gas cap.

What do you experts say about these, they are not similar so I assume only the other one will fit to 70 Challenger, but which one?



I know that the original locking gas cap is mfg'ed by B&S and it's totally different than these two ones, but they are sooo rare.
I have one such, but two cars
