Coil window shoe slate blue maybe

Hello, I am repairing some windows in a house I just bought, the top windows would not stay up, I found that the metal bits in many of these shoes and many of the pins were broken or cracked. I need to replace them. I think  the coil window shoe slate blues are appropriate replacements, need to make sure. And I am inside the appropriate pins to buy or if there is a difference. Any help would be appreciated. Thank you
