replacement spiral balances & shoes

looking for
9/16" balances
17/32" shoes

I will need at least
2x 28" barrel, 9/16", red tips
2x pivot shoes (Product Code: 15-015)

I know we will need more, but
1 cannot examine & measure all windows in building just now, and I'd like to see how well I do repairing one window on my own first.
