Ah, I see. It sounds like your top sash guides are simply broken. If you were to show me a picture of the top sash guides currently installed, we can recommend a good match.

If your old top sash guide is identical to the 18-166, then I honestly don't know what the problem can be. This is a very common top sash guide used in this industry and I've never heard of this problem before. Check to see if maybe your sashes are out of square, or if the frame is warped in some way.
