I currently have bad saddle tanks .looking to replace with a single between the rails tank. I can find tank for 68-72 but none for the squarebody. Am I missing something? my stepside is a short bed k10

Lots of good information Here on putting a blazer tank in a pickup.

Welcome to the site and as @legopnuematic states, there's plenty of info for doing a Sub/K5 tank on these trucks. I didn't buy a kit but used a K5 tank and straps along with building my on mount when I built my '55 truck a few years back. It's not that difficult.
