gas cap 70 challenger

Anyone know where I can get a gas cap for a 70 challenger?

Need more details...under a flip lid?

Yeah under the flip lid. Not a CA emissions car

Here's the 2 filler necks, figure out which one you have.

After market locking cap from Car Quest.

Then the one on the left in this picture fit the one on the right in the picture above, and the number on the right fit's the filler neck on the left in the above picture.
These are Car Quest numbers, any auto part store should be able to cross them.

Wow Thanks a bunch. I knew that you would know the right one to use.
Great pics and description, and part numbers too. Awesome Thanks Again
