spiral balances and shoes

I have 5/8" spiral balances on double hung tilt out windows from 1996 of unknown brand. Balances measure 31.5" and 33.5 inches of the metal tube. There is also a 1/2" foam at the bottom of each metal tube part of the balance which brings the length of the balances to 32" and 34" when I include the rubber pad in the measurement. Do I measure these as 32" and 34" (including the rubber pad as part of the length measurement) for ordering? I assume I need the series 600 spiral balances. (Does it really matter if the ends are black or red?)

I also need at least one shoe (so far) and can't figure out which one is the correct one. Measurement (as close as I can measure while they're still in is
1-1/4" wide and 9/16" deep. I also need to know just how accurate these measurements need to be...just to be sure I get it right.

I also need every bit of information you have on how to adjust everything. I have 15 of these windows and need to figure out how ONE works correctly before I decide what needs to be replaced on the rest of them. I've never had double hung windows before, I've always had sliders or crank out. Will all of that information come with the parts?

The 32" balances are for the top window that tilts and are currently black-tipped. The double hung tilt out windows are 68" by 32" so are really heavy. Do I still get the 600 series red tipped balances in 32" and 34" or should I get the 32" ones with a black tip?
