I am having trouble matching the broken sash guide to one you have in stock. Mine is 78 7/8" x 7/8" at the top, and 2 1/2" long. It separates into two pieces. On one side the top part only is broken.

Thanks for posting. The closest match we've been able to find is our 18-159P. See if you could use this as a replacement.
