64 c10 dash knobs?

[Mgicm]

Picked up a 64 c10 and the dash knobs are not where they should be. There are blank holes in the dash where lights and such should be and then a slide switch for wipers and a switch in the dash for metal for lights. I assume this is not as it came from factory. Would anyone have a good diagram of what the dash knobs should be and where i might get replacements? thanks!
