I am looking for these guides, four per window. About 1/2 inch long and 3/8 inch wide. The clip on in small indents on the window.

Hello!
We were unable to locate your sash guide, but we do have our white 55-034 or gray 55-035 in 6 foot lengths. These are used by window manufacturers to be used along the whole length of the sash. You could cut the lengths in pieces to match the other ones.
