If REAL GMC, it won't have a 235 Chevy engine in it, would be a GMC 248 most likely. What about #'s on the hood sides? Door plate with GVW listed? Model/Vin there? Six lugs should be 1/2-ton, Yet my Big 2-ton GMC only has 6-lugs on it's 20" wheels, different than the 10-lugs on Chevs. Open driveline? Need more info I guess.
:rolleyes:
