Broken window corner sash guide

from Mountain View, CA
My handyman bought a few sash balance from you, then found out that the windows do not hold the sash balances. After checking more carefully, found out that the plastic sash balance guides(?) are broken or too fragile to function.

Kindly identify what part should I buy? Looks like I need a bunch of them.

Many thanks
