Okay, another '57 window question. I'm trying to get all my ducks in a row: I've bought replacement screen & replacement cranks. Looking at the two or three windows that still have cranks on them, (and we'll eventually be replacing all of them) it looks like we need to cut a hole in the screen, push the crank through, attach it to the middle bar on the window, and then screw the crank into the middle brace on the frame. Is this right? Seems like cutting a hole in the screen is such a bass-ackward way to do it. Looking for any advice on this before I tackle it.
Another question I have is for the little lever that simply pushes the window out a bit...not a crank. Same application? Hole through the screen?
