Balancers help

It appears that your company have a PhD in window balancers. Could you please help me identify which balancers/parts I need to order? I have two sizes (11.2 and 23.3), all images attached.
Thank you kindly,Alex.




Hello!
Thank you for contacting us, Alex. We can help supply this balance but it will have to be a custom order due to its configuration. The pulley wheel is built into the bottom fitting itself and this balance features an extended cord travel as well as a metal channel length ending in 5/8" which is what makes it custom. For example, the metal channels should measure 11-5/8" and 23-5/8" long. Can you confirm that for us? Can you also confirm that the 11-2 balance has the same configuration as the balance shown here, other than the length and stamp?
Lastly, how many of each are you looking to order? I can draft a price quote once we have those details.
