Just got a new Brake from ENCO and took the plunge on building a pickup Bbox for my T roadster p/u build. Just waiting on the rivets to arrive to finish it. Its about 29 inches wide and 31 inches long. Plan on an all metal tonneau with a 3 bar gas cap protruding through.
Terrific work - much better than a bought in repro steel or fibreglass unit. Is that gauge a direct mechanical unit? I have one from a Cessna Birddog in the Fordson tank on my modified.
