The window channels are 29" long. The tops have 19-005 on them and the bottoms are either 15-004 or 15-005. I can't tell the difference between the 4 and 5, that's why I have included the picture. Thanks in advance for your time.

I agree, you either have our Series 380 or Series 385 balance. I cannot tell which based on your picture. You will need to carefully compare the size of your shoe to the measurements we show for the 15-005 and 15-004, respectively. That is the only way to be sure.
