Top plastic spacer/slide for a 60's aluminum sliding glass door

A quick learner from Southern California says:
Good day,

I am trying to rehab my 1960's sliding glass and aluminum patio doors. It has a plastic piece that gets screwed into the top rail of the door. That would help keep it centered in the aluminum track above and not clanging back a forth when the wind blows. I am also looking for more of the fuzzy spline that goes on the door or the case to keep out the wind. I found some of the fuzzy spline, but the fuzzy is not big enough to fill the gap. If you could help that would totally make my winter.

Looking at your pictures, I think our 84-082 top roller guide might help. What do you think? It is 1-5/16" in diameter. For fuzzy weatherstripping, look at wool pile weather stripping section and see if anything here is a match.
