Another problem that is like the turn signal switch is the dash knobs, I ordered some from Brothers trucks and what did you know they sent me the wrong ones instead of a 65 GMC knob they sent one for a 65 Chevy. The GMC is the large knob, the Chevy is the small knob. It appears that the 63 Chevy is the large knob and the 4-5-6 Chevy is the small knob. Every parts place thinks that Chevy parts is the same as GMC in this case 60-63 chevy is but not a 4-5-6-chevy. Little things I grant you, but important if you order from a ignorant parts house...Vernski
