67-69 Cuda gas cap recess all the same?

Well, digging in my storage I found not one but three recessed areas from 3 different models. The green one at the top is from a 71 Challenger, the yellow in the middle from a 69 Charger and the reddish one at the bottom from a 67 Barracuda.

I got to thinking why the Charger is different was because it used a trim ring in addition to the cap. I can’t remember if the Challenger was the same way or not (think it did). I would guess one could use the B/E body recess if the trim ring was also used.
