I started work installing the new wiper system....
Pulled the old wiper system out of the cowl and out from
under the dash, and started laying out the new parts....
Tried to install the switch, but it spins in the dash,
the original switch is keyed to a slotted hole in the dash
so it won't spin, but the switch provided by RainGear has
flats that do not match up with the hole in the dash,
so it spins easily when I turn the switch on and off....
Not good....
RainGear should have done a much better job providing
a switch that would fit properly in the original '55 dash hole....
Another view
So I cut a disk of 16 ga. galv. and drilled/filed
a hole that fits the new switch nicely....
Now to figure out how to add a tab to that disk
that will key into the slotted hole in the dash,
that will prevent the switch from spinning....
Or maybe I can just glue that disk to the back side of the
dash where the switch fits, will think about that....
