Look at the length of the arm on the wiper pivots. That will give you a clue as to how long to make the slot. The motor arm and pivot arms are usually the same length. What kind of switch do you need? Early to mid 70s Ford trucks have a two speed rotary type switch that works just right!

I'm going to try and lengthen the slot and slide it to make the arm as long as possible. I'd like to get another inch of sweep to the wiper blades. I wish I knew exactly how long to make it, but it a little tricky. The vacuum wiper motor sweeps in an arc. The electric is a full circle. Vacuum swept 3 1/2" I thought the bend in the arm and the full circle sweep would cancel each other out and make it perfect.

If anyone can give me pinouts or wiring color breakdown for Electric wipers on a 73 Hornet or anything close.
