Ken1960- is your truck an auto or stick? I have a 1963 c20-4speed that doesn't have a throttle knob. I have seen this on '60 or '61. They phased it out pretty early in the '60's is my guess, darn shame too. Maybe they kept it on the big bolts though :confused: , I just don't know. On my '63 to the left of steering wheel is choke, wipers, and lights, no throttle
I would so try to jimmy rig/replace the throtle control if you have the time, just for the novelty factor. If you have it, you will use it, would be great for jump starting other vehicles, eh?!?!?!?!!
