1965 GMC Knobs

[ChevroletC10]

My buddy has a 65 GMC 3/4 ton and we're wondering if the dash knobs from 60-63 Chevy are the same as the knobs in the 60-66 GMC's. They look exactly the same but will say the 63 Chevy wiper knob fit the 64-66 switch?

good question, I believe the knob from the 60-63 are different from the 65's. When ordering them, they're two different categories. I do know that they fit differently in the wiper knob switch.
