I thought my sweat equity might help some other bolters out there. I am nearly finished installing a 49-52 Chevrolet passenger car fuel tank in the rear frame of my 65 C10 Shortbed.
I bought the new steel tank from Tanks, Inc. (FYI: Bob Drake is also selling these tanks now too, and for a few bucks less than Tanks, Inc.) The reason I used this tank is it does not stick down to low like a lot of these rear mount tanks do and the fuel filler neck comes out of the corner instead of the top.
Check out the photo at my Webshots Link. I also have included some CAD drawings I made for this configuration and for one that mounts flush with the top of the frame rails. If you need additional photos or information let me know.
