Need replacement soring balances for non-tilt wood window lower sash

A home owner from New Orleans, LA says:
I need to replace both spring balances on the lower sash of a non-tilt wood bathroom window, and have attached a picture of the one remaining part that I have. I'd like to confirm that I need the 19" Series 500 Spiral Balance, product code S500-19 (whose spiral internal rod is 19.5", just like this one). I also need the brackets for the bottom of the sash; the one shown here is 3/8" wide by 2.75" long, so I'd like to confirm that I need bracket #X54, Product code 17-007 for those? Thanks for your assistance.

Hello! You have a good eye. We've been using the Series 500 balance and 17-007 bracket to replace this kind of wood sash balance for decades. I think the products you picked out will work out well.
