Window roller, PHP-3 Window Series 240

A home owner from torrance, ca says:
I have a Phillips Products - PHP-3 Window Series 240 Horizontal Slider.
This appears to look like the same part i'm looking for. I need (2) of them.
the holes to screw in appear very close, but i'm not sure if it is exactly what i'm looking for. (the measurements)

the length of 1 11/32 between the holes appear close, however, i'm thinking mine is more like 1 1/8, but hard to tell the difference. Can you assist me with finding the appropriate replacements?
