You have been my 'go to' company for all of the fittings in my house, built in 1975. I looked at all of the offerings you have for window rollers, but none seem to be a good match.
The roller above is 5/8" high, 7/8" long, and 5/8" wide. The mounting hole goes to the outside of the slot that the roller slides into. The wheel is approx. 9/16" in diameter.
I can't believe these wheels have lasted over 47 years.
