73 Duster 2 speed windshield wiper switch.

I need to replace the 2 speed windshield wiper switch in my 1973 Duster. I took out a variable speed electronic kit the previous owner installed, now the wipers only work on high speed, and you have to turn them off at just the right time to get them to stop at the bottom of the windshield.

Other years besides 1973 are probably compatible.
