Constant Force Coil Balance

Please help identify these parts for my window balance. The coil is 0.5" wide and the sash weighs 12.6 pounds. There is one coil on each side. Also is there a way to replace just the metal shoe on some of the windows without removing the entire unit? Some shoes have cracked (the metal cylinder that the window fits into).

Thanks in advance!

Here's what I'm thinking for these parts:
15-175: Coil Balance Shoe, Slate Blue
S152-6: 6 lb. Series 152 Coil Balance
15-144: Coil Bushing Cap
15-145: Coil Support Barrel

Please confirm whether I've got these right. If so, I'll go ahead and place the order.

Thanks in advance!

You have done a good job identifying your coil balance parts. I would add the other side of the coil support, 15-143. The three support pieces go together like a sandwich, with the metal coil in the center. Your window seems to weigh a bit more than 12 lbs. You might want to double check that. Two 6 lb coils will carry 12 lbs of sash. I'm afraid that the metal cam in your pivot shoe is not available as a separate item.
