Hi there- thanks for posting!

Yes, they are Silverline windows. The tilt balance would be S765-33 with a spring weight option of 3230. The pivot shoe has been replaced with our 15-046. Carefully compare all measurements and information to what you have and get back to us if you have any questions.
