and if that isnt enough, wait till you see that you got the drivers arm slightly higher than the passenger arm and you have to take it BACK off and turn it slightly and do it again. haha good times.
So if you have a close look at the first couple of photos you'll see a spot where a tooth came off. I was trying to push it on and suddenly a little shiny metal piece falls off. Looking at the wiper mounts there are twice as many teeth as what's on the wiper arm. They should be able to fit on anyhow you place it. After taking the photos I tried again, and another tooth broke off. I might try again today, maybe with some sort of lubricant. The metal spring tab is supposed to be pushed out when the arm gets pushed on, and that tension is what holds the arm on. Still, I don't think it fits.

I removed the passenger side too, and then, since no wipers would be dragging across a dry windshield, tried turning on the wiper motor for the first time. I was expecting strange, weak, or poor performance from the vacuum design, but what I got was wholly unexpected. I thought the dash mounted switch moved one way for on, and one way for off. What I got instead was move switch one way for wipers to move in one direction, move it back to get the wipers to move the opposite direction. This doesn't seem normal to me. Is it really that in the 50's you'd have to reach up and move that lever each time you needed a wipe?
