Hey, Jerry. There are many, many different varieties of top sash guides. I cannot tell what you have, but if you are able to remove the undamaged one and take a picture of it by itself we can make a suggestion! It will also help if you provide dimensions. Thanks!
Thanks Tom, I did remove one and checked the dimensions with ones on your website and found one that I believe is correct. It is white, but figure I can use a marking pen to color the top of it, which is the only part that shows. I did place an order for several of those, plus a channel balance that I found broken on another window. Thank for the help and the YouTube videos are great for diy repair folks like me.
