Looking for parts for MW WINDOWS

Hello!

It appears you have a tilt window spiral balance like our 3/8" diameter Series 900 or 5/8" diameter Series 600. Measure the outer tube for your old balance to see which one matches best. We'd be happy to help with the pivot shoe but we will need to see an undamaged version removed from the track along with the written out thickness and width dimensions. 

As for the pivot bar and T-lock shoe, see our 15-195B and 26-366. Compare the dimensions for these parts with yours to see if they match up.
