The ribbed area of the wheel opening has thicker rib than a pickup . So it comes out slightly below the door . Chevy and GMC compensated on the big trucks by putting a little scabbed on rocker molding . This add on rocker molding matched the profile of the fender and is wider than the original rocker molding. Its not much taller and mainly in the ribbed area. Probably a 1/2 to 1 inch . I believe the hoods will interchange but thru 55-57 but would have get the tape measure or the impact out to be sure . Plus the front area that meets the grille supports is a different shape and will not match to the pickup. I just cut a big truck fender to grill support area to a guy that is converting a 55-57 Chevy pickup to the big truck grille . He is using pickup fenders with the big truck (boob style grille ) . Also have to convert the upper grille cross bar. I have never checked the actual wheel center opening of a 1/2 ton verses 1 1/2 ton. I will do that sometime . If you were building a 4 x 4 with large tires that would be a nice setup to use. Good luck .
