Window balancer and shoe

A quick learner from Haddon Heights, NJ 08035 says:
The balancer is 28" long in somewhat flexible white plastic with black tip. About 7/16 in diameter.

I also need two shoes.
This window only the bottom window is moveable.
Also do I need to notch the track near the top to replace the shoes.

Paul from SWISCO responded:

From your dimensions and photos, it looks like your need our 5/8" diameter S600-28 with a black tip. Your pivot shoe is no longer available, but we suggest our 15-046. This is 1-1/4" wide by 1/2" thick. Please compare and look over our media guides to further help you. If you have any questions, let me know and I'll be happy to help.
