Channel Ballance non-tilt window 1/2" channel width

A quick learner from Denver, Colorado says:
I need 4 Channel balances for 2 non-tilt windows.
The channel is 1/2" wide and 29" long
It appears as though I need a 19-009 Top (1/2" x 7/16"),and a 15-04 Shoe (15/16" x 1 3/32").
Based upon the picture, does this look correct?
I do not see a channel balance series that uses this combination of Top and Shoe. Do I need to order the parts separately and assemble myself or will you do a custom assembly?

Thank you for posting. Unfortunately, the manufacturer of your window was Acorn that went out of business quite some time now. Instead of 15-004 shoe we use 15-003 shoe as a better fit in the window. With that in mind, I recommend our S710-29 side load balance. The stamp weight option is the number printed on the metal balance channel.
