Hi:
I am here with attaching photos of window lifting mechanism gone bad. Do you have these parts?
This is for Series 8500
AAMA/NWWDA 101/I.S.2-97
H-R20-48X78
H-R35*-36X64

There are two different parts for two different windows. I would like to get 2 each.
Do you have them and the price for these parts?

Sure, I'm confident we can help. Looks like just your pivot shoe is broken, so see our 15-180. This looks to be a great match.
