Default problem with replacement window rollers

Last month I installed new window glass, weatherstripping, and all-metal rollers in our '59 convertible (see Donna's '59 resto-mod convertible). Yesterday I hooked up the window motors to check for smooth operation. Three out of 4 worked fine but the passenger side quarter window stuck after briefly starting down. It turned out that the cupped washer that slides along the track had been pushed through to the opposite side and the roller spring was causing the mechanism to bind. I figured there were a couple of possible causes; either the track had wide spot or maybe the cupped washer was of improper diameter. I removed the window today. The track was OK however the cupped washer looked to be the problem. While it was only fractionally smaller than the diameter of the track-riding part of the roller, the after-market cupped washer was considerably narrower and much less "deep-dished" than the OEM cupped washer. Each of the cupped washers on the new rollers was similar to the one pictured. I am salvaging as many of the old OEM cupped washers as possible and will put those on the replacement rollers, especially for the quarter windows. Pictures attached (the close-ups are a little out of focus...sorry).

#2 roller with cupped washer pushed to other side of window track and binding on spring
#3 roller with cupped washer in correct position and spring compressed
#5 concave side; new washer on left, OEM washer on right
#6 convex side; same arrangement as before
#7 convex side, lower picture angle; differences between new washer on L and OEM washer on R are clear; notice wear mark on old washer with plenty of width left to remain on the track.
