Custom Balance inquiry

I need twelve (12) #2740P 28" and two (2) #15B 16" channel balancers. Width on the balancers are approx. 9/16" X 5/8" deep. I am enclosing photos of the items. Both 28" and 16" have the same ends. Are these still available?

If it is a problem with making the tracks, I could repair the ones I have. I only need a few springs and plastic ends.

Those plastic pieces are not damaged or missing, they are fully intact from one of the good ones I have. I'll get a better, closer set of photos for you to see what we need. The first two are from one end the last three are from the other end. Let me know if you need any other information. Thanks!

I am pretty sure I found all the parts I need. I am going to order the stuff. Thanks, Albert
