Challenger Flip-top Gas Cap Differences and Question

[73Dodge]

Kind of a weird place for my first post but I had a question along the lines of this topic so... Hello everyone! On my 73 Challenger, I have the flip top cap with the rubber bellows and a locking gas cap. Is there a non-locking twist style cap available? I have been searching and just can't find anything compatible with the filler neck and the flip top that doesn't lock.

here is the cap off of my mid-July '70 Challenger R/T 

I believe it is the original - even has some "Earl Scheib GREEN" overspray on it

rubber seal to locking cap - no helper spring - blind roll pin at hinge & release (so it can't be seen from the top when mounted on a car)

the "Locking Gas Cap w/Flip-Top" was the only OPTION, $4.40 in '70 ( not available separately ) & it was discontinued during the '71 model year

My 73 Challenger has the twist off cap at the filler neck and flip out cap outside. I replace the twist off cap with a locking cap to avoid vandalism. So it is available but why change?

Thanks Dan!  Very helpful.

I'm also curious how to remove the release button with the blind roll pin?

From a similar discussion over on Moparts:

Me:  Thanks for the replies. I drilled and tapped the roll pin for a 4-40 machine screw. I need to run out and get some 4-40 screws and will try to pull it out/tap it out that way. I've been soaking it with kroil. Will report back with results.


Moparts member suggestion:  Run the 4-40 screw (with a washer) through the ratchet end of a 1/4" drive socket.  Then thread the screw into the roll pin. As you tighten the screw the socket should bottom out against the frame and as you continue to tighten it will draw the pin up into the well of the socket.  Used same method to pull blind threaded dowel pins on machinery all the time.
