Thanks for reaching out! Your pivot housing appears to be our part 15-087. Take a look at the diagram below and compare the measurements to confirm that this is the correct fit.

Detail of 15-087

This housing is compatible with our Series 180 Coil Balance springs. To confirm which spring strength you need, you'll have to take a look at the coil springs to see if there is a stamp/marking. If there are no stamps/markings, you'll need to obtain the exact weight of the sash and divide it by 2 to confirm the correct spring strength.
