Top Sash Cam guides (Black)

The white ones pictured are replacements and seem somewhat new-ish. Though I'm looking for Black Nylon if Ic an find them for a reasonable price point.

Top hole looks to be 3/16 on center from the top.
Bottom hole looks to be about 1

I was having difficulty finding the perfect fit. though thats one on my list as a good contender. the pilot hole alignment seems correct, but the depth is shallow and the height of the catch is 1/8 inch taller.

I'm going to take a window off when the weather permits and gather some more precise measurements of the channel itself. seems like it might be one of this left side right side sets. and the black ones are also really old replacements. They too, don't seem to be a perfect fit for the channel.

I'll get back with those measurements from the window channel drawn out ASAP.

Attached are screenshots of my sketch file. I'd send you the file but your system doesn't allow uploading it
