Need help trying to find the balance and also included one pic of a guiding wheel for the window next to it I cannot find.

Thanks for posting. This balance looks like a S380-33 or S385-33. The only difference between these two balances is the 'depth' of the bottom nylon shoe, so compare both with your old hardware to see what matches best. You will need a stamp option of 3240. As far as your window roller, I am not certain if we have a replacement. Can you provide dimensions of the housing and the diameter of the wheels? In the time being I am going to see if any of my senior colleagues have ideas. Thanks.

Thank you for your patience with us. For your sliding window roller assembly, could we have you get back to us with the width, height, length of the housing, and diameter of the wheels? We'd also like to see a few more images from different angles. Thank you.
