Are these the right coil parts?

A quick learner from USA says:
The actual weight of the window is 23 pounds.

Each side of window had two coils; will order four S150-6 six pound coils

Also, want to replace all these parts for new
four 15-146 Coil bushing with flange
four 15-147 Coil bushing Cap
four 15-140 Coil balance shoe

I have saved all my screws for the flange. We're probably going to order double everything as this is one of two windows.

Please confirm that our photos match my opinions on the parts to order.
