I figured that these are s380 rails 29” long. But the only stamp on them is 28C so not sure on the weight rating to pick.

Hi Aaron,
I do agree the balance you have here does look similar to the S380-29 channel balance but I believe you may have a show with a 7/8" depth. Would you be able to double check and confirm this? If my assumption is correct, the replacements will need to be a custom assembly.
Regarding the stamp, we typically recommend using the 2830 stamp option but you'll need to double check that your sash weight is 16 to 23lbs.
