replacement parts

A home owner from Arizona says:
the balance spring has a 7 # 35 on it? these parts came off of an MI window model # 350. I need both the right and left spring and shoes along with new sash pins

It looks like the stamp reads #7.5 35. Take a look at our 15-199 pivot shoe, S160-7 coil spring, and 26-378 pivot bar. It also looks like your support is damaged, so see our 15-150T, as well. Carefully review this hardware to confirm that it is the same as yours.

I need a a pivot bar that has threaded holes? does the 26-378 have a sister with threads? lol your help would be extremely appreciated

The 26-378 is made of die cast metal, which is a soft enough that it will easily thread as you install it with a screw.
