Aluminum Single-Hung Window Bottom Sash Guide

Hello,
 
I am trying to identify a replacement bottom sash corner guide / sash shoe for an aluminum single-hung window in a brick-and-beam loft building.
 
One of the two bottom sash guides is missing, causing the sash to twist and blow open in the wind. I have attached photos of the intact guide on the opposite side, along with measurements.
 
Here are the key details:
 

Window type: Aluminum single-hung (bottom sash slides up/down)
Part needed: Bottom sash corner guide / sash shoe
Track width: ~9 mm (≈ 3/8”)
Guide length: Just under 2 inches (~48–50 mm)
Guide depth into track: Only a few millimeters (~3-4mm)
Design details:

Offset / angled tongue that rides in the vertical track
Guide slides under a metal keeper/retainer in the frame
Long rectangular nylon/plastic body (not a balance cam)

 

 
 
This is not a vinyl window and does not use channel balances or sash cams — it is a guide only.
 
Please let me know the correct replacement part number and whether it is left-hand/right-hand specific. I’m happy to provide additional photos or measurements if needed.
 
Thank you very much for your help.
