Need replacement window parts

Question

I am hoping you can help me with these window parts. The longer piece is broken. It has the number 801030. The pivot lock is still in one piece. No number is on this part. The window would not stay up due to the broken part.

This looks like a 15-228 Pivot Shoe, which uses either 1/2" thick Series 160 Coil Balances, or 3/8" thick Series 165 springs. You'll need to remove the old assembly and measure the thickness of the springs to determine which you need. The video below shows how to remove and replace coil balance systems.
