Pivot Bar question

Dear Swisco: I have a beach house with vinyl windows. I am confident I can replace the pivot shoes and spiral balances that have rusted. However, on some of the windows, the pivot bars have rusted badly, and I cannot determine how to remove them from the window frame. The bars seem integral to the vinyl frame, and it is not obvious to me how to replace them. Attached is a pdf file showing my windows.

I sincerely appreciate your kind assistance, and thank you for the excellent web site with the wonderful videos.

Paul: Sorry for the delay in getting the images back to you. The windows are from our beach house, and I have not been there for some time. As you can see, I have done a poor job on maintenance and lubrication/rust prevention. I have tried to show some images where the pivot bars have rusted to the extent they no longer are connected to the slides in the sash. Can these pivot bars be replaced. I frankly can see no simple way of removing them. I really appreciate your kind assistance.

Hey DAve: This is the correct tilt bar part. Thank you. I have to also replace a few spiral balance tubes. I have 5/8" series 600 tubes (plastic tubes rather than metal). I have 3 different size windows, and the tubes proper measure either 16.5", 25.5", or 28.5". Should I round each length up to the next whole number (17", 26", and 29" respectively) for ordering? The tips are white.

Unfortunately, I did not measure my pivot shoes (windows are at the beach house). From the image above in the previous thread can you ascertain what pivot lock I will need? Is the fact that the housing for the pivot bar is blue suggest it is a 15-015?

Also, from the images above, can you suggest what type of sealing strip I would need at the bottom of the window?

Thank you for your patience and assistance. I appreciate it.
