Sunroof roller ? anti rattle bushing? what is this called

[bossrobot]

Hello E9 forum,
I bought my car partially disassembled and now have the sunroof back together and working. The guy before me bought new cables and I noticed that these little round rollers (in pictures w/arrows) are not on the old cables or the new ones.
I think I see what they do, but have no idea what they are called or where to ask for them ?
Any info would be much appreciated !

Welcome to the Forum mate.
I'm in the middle of putting my sunroof back together as well.
My roof doesn't have those rollers either.
I could be wrong but suspect the rollers are there simply to prevent rubbing.
Your new cables might be from a Porsche as many of those parts are interchangable.
Have you got the 2 x plastic triangular spacers to make the back edge pop up - these frequently go missing.
If you are having any problems with reassembly let us know.

Thanks Wes
I got it all back together and it is working well. I was looking at it and thought that those rollers might sit up on this part and keep the roof in place when its open? stop it from wiggling?
