Need Gas Tank Pics Panel Truck

[ji240z]

Hey Guys. Newbie here to the 60 - 66 Chevy truck. I just purchased a 1964 panel truck.( Also recently a 55 step side.) Much work ahead of me. The gas tank was out of the panel truck and refurbished when I got it but in trying to put it back in, the tank lines up great but cant for the life of me figure out the strap. Can those of you willing post a few pictures of the strap ( i believe its just one ) and the way it mounts. there is definitely something homemade about mine.
