The conversion looks great Chris. What did you use for the air reservoir? I had planned on using truck mounted couplers, but your body mounted conversion looks better I think.
It's a section of a toothpick with a piece of thread tied around it. You could probably do truck mounts. Instead of notching the end sill you will probably need to remove most of it. And possibly raise the body up a hair. BTW the tank splits in half at the railing longways. Pretty neat design.
wow! I have been busy as of late and have not been checking much lately, great stuff! Always amazed by your work Chris. I couldn't help but noticed you also painted the cross warning sign on your street. Nice touch!
