Ballasts for impact window

Home Owner from Florida
For the 52X49.5 the marking says 2.3 .7 .10. For the 36X53.5 I see 12 10.

Thanks for reaching out to us! The coil balance assemblies you have here are the Series 210 Roller-Tilt balances. For the assembly in the first photo, you'll need the S210-22 since the housings are marked with a 12 and a 10. 

In regard to the other assembly, are you certain the stamp on the housing pivot is 2.3? It may be a good idea to confirm the sash weight to ensure the correct balances are being used for the repair.
