Well done Patrick...seems to fit what folks would've done in the 60s!
We used to use a Tecate bottle vineyard wired to the tube and radiator upright on our old sulfer buggy...bare car chassis and motor, bench seat, ugly assed welded irrigation furrow pipe for a temp gauge and steering column to hang from...tractor gas tank and sulfer machine out back. Think of it as a really ugly sand rail. Just hauled butt down the vineyard rows to keep ahead of the sulfur blowing out. Look at a vineyard row next time you get a chance...damn tough to keep an overpowered-vague steering-on junkyard tires farm implement like that moving straight.
My early Bronco has an MJB coffee can screwed into the firewall. The first owner was a lineman for SoCal Edison up in the Sierra west of here...kept a quart of
oil, some coolant and an old red rag in it. When I was buying it and pointed it out, the old man, serious as can be, told me he liked MJB but I could use any other brand's can I wanted to.
