Window balance

I need to replace my balance and shoe on my Windows. Pictures are attached of mine. I need tilt 14B and 12B for a kitchen window. I bought a couple of the t- lock 1 1/4 ones for my balance but they don't clip into my balance correctly. Just a tad short. The cam fit into my plastic shoe and worked and the shoe would of worked but it wouldn't clip under the rivet in my current plastic shoe. My cam completely fell apart like rocks. But my plastic shoe needs replaced too because it's cracked.
