I just did this job a few months ago so it is a bit fuzzy, but I am pretty sure you just take the door panels off, carefully, and then take off the furry strip that the window passes as it comes up out of the door. Then you have to find the screws that hold the vertical tracks in place. Unscrew those and wiggle those tracks and get them out of your way. Then after unscrewing the two bottom screws that grip the bottom of the window, you can start to wiggle the window and turn it diagonally so that the corner (back corner I think) pops up through the top slot where it usually travels. Grab that corner and pull it out through the top on the inside side of the window frame. Same exact thing going back in. You can get those little pivots that attach the window handle arm to bottom of the window pretty cheap too if you need them.

I think that is it for the '66 230s.
