Parts ID help, cuda fuel filler tubes and tank straps

Hi all, I've got 2 fuel filler tubes for cudas. The straight one seems to fit best on my 69 vert when I hold it in place. The curved one not so much, but hard to tell without the tank installed, and I'm not at that point.

Also gas tank straps? I have 2 the same and 1 different? Looking for my 69.

Thanks
Steve
