In my experience, even with just "Off", "Low", and "High", it's not much fuss. And on those misty days where the sky can't make up its mind whether to drizzle or not, a gentle tap of the windshield washer pedal will kick the wipers over to clear your view. I like it that way.
IMHO, not worth drilling new holes, and figuring out how to mount a Camaro/Firebird motor, linkage, and wire it all up. Not to mention finding a switch that won't look like you've butchered your dash.
