Window replacement roller assembly

A quick learner from Roseville says:

23 year old windows and many need new roller assemblies, the plastic has worn where the metal rollers are and now the windows drag on the plastic and not on the roller. Would like about 20 assemblies.

The latch on the window says "Pacific Industries"
Attached are two photos and a drawing with dimensions.

Really appreciate the help. Thanks!
