Being that these are old wood windows, I suggest our Series 500 5/8" non-tilt balances with 17-012 balance brackets. These were used by early wood window manufacturers in the previous century. The brackets hook onto the balance spiral.
To install these balances, you would drop them in from the top, on the side of the sash. Use a 33-017 screw to attach the balance tubes at the top. Now, raise the sash, and have someone hold it up while you attach the 17-012 bottom bracket with a 33-090 screw, while the U-shape opening corrals the spiral. With your finger, bring up the spiral to the bracket and attach the 75-005 tool, turning the spiral clockwise three turns and hooking it to the fork of the bracket. Repeat this process on the other side, and try the sash. If sash creeps down, raise and hold up the sash, giving the balances another turn or two. Finally, to figure out the balance tube lengths, get the height of the glass and add 1" for the top sash and 3" for the bottom sash. |

I am sorry to say that we do not offer that. Your best option would be to go to your nearest mill work and they will be able to provide jamb liners for wood sashes.
