Thanks for posting. You most likely need an S380-31 Channel Balance, with a stamp option of 3030. Just make sure the 'depth' of the bottom nylon shoe is 1", as shown below.

Comparison of the S378, S380 and S385 balance shoes.
For the Top Sash Guide, see if the 18-124P Rollyson guides match what you have. Let us know if you have further questions.

Thank you. Took a pic of the depth. Not sure if it's 1 inch or 7/8. Want to make sure I order the right items.

We can't confirm based on a photo but it does look like your shoe measures under 1" deep. If so, the 7/8" deep S378-31 (3030) balances would be the way to go.
