Technical Help id dash knob/switches

Picked up a new project and missing quite a bit. Dash knobs are not stock and trying to figure out what they came from. Can anyone identify? Thanks

 

Figured it out after digging for an hour. 58-60 Chevy impala. Came in a 54 Corvette project and there is NO way I have the budget for original hardware so 1960 impala dash knobs it is. Thanks

 

My guess was 1958 chev. Our family ride back in the 1960's.

 

60 Impala not the best pic. but you figured it out.

 

Just saw this & I was going to say '59.
They're nice to use, esp when you don't want to look at them while travelling down the road.
However, I don't recognize the one w/a push-****on. Wasn't on my '59 Bel Aire. W/s squirter, or what?
