I am looking for replacement parts. I need the tilt sash lock in the photos and also the correct coil spring. The pivot shoe holds the coil and can be reused. See photos. I was unable to fnd the tilt lock on the site.
It slides into a pocket at the top of the sash frame
Broken coil balance. the pivot shoe / coil holder is ok.
The side of the shoe has 8R on it and the coil has 8FD on it.
Is it safe to assume it is an 8lb series 180?
