Window Channel Non Tilt Single Sash Window (PGT)

I am trying to make a repair of my no tilt single sash window and the right channel is in up the position as a plastic tab on window is broken.

Left channel moves up and down with window but in current condition, window want to come out when raising.

The stamped number on the channel is 29 4 FV CMC 7.

Any assistance you can provide I the ordering of the right parts are greatly appreciated and will make the necessary order.

The link to add a picture does not work and could not send pictures for reference.

regarding the parts needed to replace the channel guides, clips and any other items I may need. I have not weighted the window per say but can say it is at least 25 lbs. if this a factor. The window is manufactured by PGT and installed in 2003.
