Thanks for posting. See the S380-26 or S385-26 Channel Balance. Depending on the shoe depth, one of these might work for you. See below. For a stamp choose 2530.

Comparison of the S378, S380 and S385 balance shoes.

It is the s385. Is there a left and right side or are they interchangeable?

The Series 385 is non-handed, so it can work on either side of the window without issue.

Thank you for your help. When i go to order it has a bunch of different options from 2510 to 2570. Is there a certain one I would need ?

Your old stamp reads 25-3, which translates to our modern 2530. However I always recommend that you weigh your sash on a scale and check the weight chart to verify that this is correct. Stamps can vary for any number of strange or unexpected reasons, but the hard math never lies.
