Boler door window

[Mandy in winnipeg]

Alas after a freak gust of wind caused the door to slam and break the window, I took it apart and had plexi put in. Bring it home, put it back in....all is going so well so far!
UNTIL- I discover a very important piece is now missing.
No idea what its called- but comparing it to the kitchen window, it looks like a wee cylindrical piece is missing, that fits throught the hole at the end of the arm, allowing it to run up an down the channel in the centre piece of the window. ( phew! so many words for such a tiny missing piece!)
Anyone got any idea where I would find that little , albiet important piece ??

The 2nd pic is of the kitchen window- but shows the bit I am missing.

Thanks so much Rick.
I did look on there , but the Friction Pad doesn't look like the mechanism I think I need ? I've posted a 2nd pic. What do you think ?

Good day Mandy in the 'Peg. You may have not scrolled down to the bottom to see a breakdown detail of the part in 3 pictures. Picture 3 shows the piece folded over and connected to the hole in the arm. I was confused to until I found this and read some of the reviews for the part. One of the reviews had complained that the picture was not self-evident. Maybe as an after thought, they added the 3 pictures to the bottom of the description. Hope this helps.
