Window roller replacement

I'm a local handyman and am not too familiar with the window 'glide system' I ran into yesterday. A customer has original (late 50s/early 60s) original aluminum windows. Complaint was tough to open / close.

I removed the window and found remnants of old rollers and (2) axle pins without any rollers (original appeared to be polymer similar to those found in drawer slides) but I don't have any dimensions. The axle pins appear to be riveted as I was unable to unscrew from window frame.

What info is needed and will I need to drill out the pins?

How would I go about mounting the new hardware if I need to drill out the existing axles? Thanks for your expert advice. Steve

I'm not sure if you could use the 87-192 or not. I would like to see a photo of the window, the original roller, and how the original roller was installed. That would help us figure out what to recommend. Thanks!
