Complete Coil, Pivot Shoe, Support Cap, Flange, Barrel

I'm looking to replace all the components (coil balance, pivot shoe, support cap, flange, and barrel) for my Weathercraft vinyl window (44" width, 22" height, 28Lbs). Please provide guidance on the following:
1.) Part numbers to completely replace the coil and related components.
2.) Coil weight recommended for 28Lb windows.
3.) The attached photo shows two Coils per side of window. If two coils are still needed per side of window, please provide instructions on how to daisy change the two coils to achieve the desired balance for the window.

Thank you,
Martin

I've attached three pictures of the pivot shoe out of the window.

Thanks.

Any update on my latest response?
