Looking for replacement balance tube and also maybe vinyl track

A quick learner from Chicago says:
Hello,
I have some old Marvin wood double hung windows that need replacement balance mechanisms and maybe vinyl tracks as well (also maybe the insulation on the bottom of the window).
Can you help locate the correct parts for me?
The Balance tube has: 28HD on it.
The windows say: MARVIN 01 IGCC CBA 87 on them (so I think that means that they were made in 1987?)
User submitted photos of window hardware.

Please see our S751-29, I think this could be a match. Let me know what you think.

I'm afraid we do not sell replacement vinyl jamb liners.
