Filler neck help!

So if I'm reading this right ..

You want to go back to a standard gas cap. (Locking or non locking,)

Looking at your photos you are going to need to get a replacement filler neck.

Yours has been modified and the stock part to tighten a stock cap is gone

Correct. I’d like to use the original locking cap. I can’t seem to find the right filler neck though? I keep seeing ones for fold down rear seat Dart Sports that have the angle to them. This is just a straight pipe I think?
