My '31 Bud Cab Pickup came to me with a hand wiper. The rubber was completely rotted so I bought a replacement from one of the vendors. That didn't work either.

I then took everything off and plugged the hole. Purchased an electric wiper system from Newport Engineering. Perfect fit and works like a champ. This even gave me a wiper for the passenger side as well, which my wife appreciates a lot.

This would be perfect for your installation, especially since you have quite a bit that's not stock anyway.
