Well, I've been away for a while due to traveling for work, but some of you know I had some interesting things going on with my defroster for my 55 Wagon. Well it gets more interesting. As I intend for this to be my year round every day driver, I clearly want to get everything working as best as possible, so I was investigating how to properly fix the defroster when I found that when they changed the wipers to electric motors, they mounted these motors (1 for each wiper) up against and touching where the hose should connect to the dash for the defrost.
So my question is this, What is the chance/cost of reverting back to the original cable and pulley wiper system? The only part of the system I still have is the vacuum motor under the hood (which I will likely change to the electric motor upgrade I have seen on here). I have seen the pulleys for sale but they require a core that I don't have.
Or, is there some other option that I am not seeing here?

Thanks for the help
