i thought they were all the same, same cowl, same switch location
i've had 58-59 trucks with both vacuum and electric
my 58 has electric that i pulled out of my 59 panel
it had the cable operator on it
when i shaved my dash, i used the throttle cable in the hole next to the headlite switch to operate them
you can see the knob is out a bit here, out is off, in is on.
they work, just never used them
rain-ex is your friend


if you buy the motor and it needs a cable operator, i have one you can have
