Thanks for posting. Your pivot bar looks like our 26-226 and the pivot shoe looks like our 15-175. Just make sure the dimensions are all the same. For the coil springs, see our Series 152 coil.

Thanks for your quick response! As a follow up, what do you recommend for the balance supports/covers? Does the shoe (15-175) have connections for 2 coils? And last, is it OK to mix-and-match coil weights to achieve the desired total weight? So, for a 29lb window each side would have paired 8lb. and 7lb. coils.

If you also need the covers, our 15-144 clip and 15-145 barrel are meant to be used with the Series 152 coil spring. The 15-175 can use two coils, yes. As for mixing and matching strengths, you could do that as long as both sides use the same exact combination.
