Looking for sliding door hardware from aluminum sliding single-pane door

Hey there,

I'm on a quest to repair the single-pane sliding patio doors on a 1978 built house in the SF Bay Area.

The doors are otherwise in excellent shape and replacing one would stand out like a sore thumb, so I'm trying my best to repair the existing ones!

I've attached photos of the hardware I'm hunting down.
Firstly, looking for the glazing wedge gasket that holds the glass in place.
Secondly, looking for the weatherstripping from the door edge to fixed glass seal.
Lastly looking for the aluminum extrusion of the bottom frame as it's ground down the track from having a collapsed wheel. That section is 8'.

Any help would be appreciated.

Thanks!
Chris
