Please help me verify that I've chosen the correct replacement parts

A quick learner from Girard, PA says:
Parts I believe are correct:
26-226 Pivot Bar
15-178 Pivot Lock Shoe
S600-17 17" spiral balance

Does this look right to you.

Thank you!

ALso, if you don't have the spiral balancing tool is it still possible to install new balance.

The parts you picked out look pretty accurate, yes, but you will need to make sure the dimensions we show in each case will work. That will be the ultimate deciding factor and it isn't something I can really eyeball in a photo.

You don't need a charging tool, necessarily, but it will make your life a whole lot easier. I recommend it.
