60-66 Chevy And GMC 4X4's Gone Wild

[GMCBURB]

Maybe too obvious but a couple of differences I'm aware of are with the grill letters and hubcaps. The 64-65 grill letters (G and C) were oval shaped while in 66, the G and the C were more squared off... plus the 66 had a groove running though the letters which was painted red. The hubcaps for a 66 had a raised ridge around the center and also at the edge of the three pointed star shape (or whatever you call it). The 64-65 hubcaps were flat here.
