I have a 58 f100 but before the split off of the fridges you guys helped me a lot and I really need to get this done before it rains again.

So I installed the delayed wiper motor and switch. I got it all working but the throw on the drivers side wiper is way to far. It parks fine on both sides and on the passenger side it goes to just before the curve in the windshield (perfect). The drivers side goes all the way to even with the park. So the passenger side is about a 100-110 degree throw, but the drivers is 180. How do I fix this? The actual arm linkage has not changed.

I can't help you with your issue, but I am interested in putting delayed wipers in my 56. What switch/motor are you using? Do you have directions on how to do this?
Thanks

I followed Walstons directions, from his gallery.
