Replacement coil balance shoe

A handy person from Havertown, PA says:
Need help with correct parts identification

The spring has the number 407 stamped on the end.
The other parts do not have any ID numbers on them

The attached pictures may help.
Thank you for all of your help

Thanks for posting. I recommend our 15-155 pivot shoe, 15-156 spring cover, 15-157 balance drum and our S170-407 coil spring. Keep in mind you can just replace what is broken. No reason you can't re-use undamaged parts.

Everybody at SWISCO is so great, can't thank you enough.
I am going to replace everything as recommended since with my luck, I'll replace one thing and then a short time later something else will break.
Better safe than sorry.

Again, thank you for all of your help.
