Cab Welding checking instruction.
Rusty Dog, the sheet you need should be 1.07. Also, additional dimensions are given on sheet 63.02 and 63.03. Also sheet 31.00 and 32.00 shows detail on floor to door pillar welding. Be careful that the sheets you reference in the assm. manual are correct for your model, as many drawings are for larger trucks. The centerline of your cab is a main reference point for cab mounts, hinge bolt holes etc.
DOZX, I had to pie-cut my inner to outer cowl panel at the top and where the bottom makes the radious to the "rocker", side sill. Did not have to completely tear it apart and re-weld it. I was fairly disappointed with the quality of this part, looks to me like they could do much better. If Dynacorn would release this part separate from their complete door frame, our problems would be solved. They are the manufacturers of the complete cab, assembled by Premier Street Rods and used by Icon, among others.
