CIMTEX RODS SUPER CAMEO: PART 10
In part nine of our Cimtex Rods Super Cameo Buildup Series, we covered the installation of the Classic Industries Parts and Accessories reproduction ’55-’59 Chevrolet/GMC lower door hinge panels, doorsill rocker panels, upper and lower door hinges, new right- and left-side front floor pans, inner and outer lower cab patch panels, and right- and left-side truck cab supports. To put it in a nutshell, the crew at Cimtex Rods in Jarrell, Texas, basically rebuilt the whole bottom end of our Super Cameo ’56 Chevrolet big window truck cab from stem to stern. Now, with a rock-solid truck cab firmly bolted onto our Cameo’s highly modified C4 Corvette-suspended truck chassis, we closed with the promise that we would be installing a new set of Dynacorn International Inc. ’55-’59 Chevrolet/GMC reproduction truck doors, followed by angle-chopping the top on our ’56 big-window a total of 3-1/2 inches in the front and 3 inches in the rear. Unfortunately, things didn’t exactly go according to plan.
