clarify spring balance header & footer parts

A quick learner from California says:
Please help me to identify the header & footer of spring balance. Please see 4 pictures of the footer and 4 pictures of the header. Along with one picture of the sash spring balance.

As far as I know I have a wondow manufacturer named Philips. These sash spring balance came from single hung (non-tilt) window measured 33"wide and 23" high. The height of the metal appears to be 5/8" and the 1/2" size apeared would work(although it appeared to be slightly wider than 1/2").

User submitted photos of their balance attachments.

Good Morning,

Your balance replacement is our S385 which features the 15-004 shoe and the 19-005 top.

There is no tax since you are a California resident and we are located in New Jersey.
