Technical 33-37 pickup fuel tank between 32 rails

Looking for options to replace the under seat tank on my pickup. I have a Vintique 32 p***enger tank that will fit but not sure how I would route the filler neck. The 33-34 would work if the dimensions for mounting work. Anyone have suggestions or know if it will fit ?

 

Some ideas here:

@krylon32 likely has some experience with '32 pickup.

 

Had a look at that post as well.
