A little more update: once the cab was back together, took the truck to a buddy to get the frame step notched. Then redid the fuel system, a Boyds welding tank fit the bill quite nicely. Also swapped in some chrome, and decided that patchwork primer wasn't a good color. Ended up settling on some Rustoleum Vintage teal as my new color of choice.
