Do you carry these parts in stock?
I believe mine are Series 380 then. Mine have 28 C stamped. Will this make a difference?

Thanks for posting! Your balance shoe appears to have a 7/8" depth. That said, your replacement balances will need to be custom assemblies made with the 19-005 balance top and the 15-029 winged balance shoe. They will have a 2830 stamp option, which can support a sash weighing 16 to 23 lbs.
Be sure to double check that the length of the metal channel is 29", not including the attachments.
I'll also need to know the number of balances you intend to purchase to create the quote. There is a quantity minimum of (2) balances.
