symbol sliding window runner trim

Hi  folks  .  i  am working on an auto sleeper symbol  its a 1999 model  .The customer would like  the    plastic  (i think) trim replaced that the plastic window slides  in,  the  one behind the drivers door on  o/side.
Has anyone repaired one of these frames  .I  need to know  where  i can get that  runner trim from  ,and process  of replacing it  .I have a feeling  it may be a window out  job .Any  advice greatly appreciated .

This post my help, its a bit old though [You must be registered and logged in to see this link.]

Brilliant info  thanks  very much

You can get the new rubber channel from Autosleeper. 
The brittle old trim will slide out - lever the channel out at the driver door end and then pull!
For clean-up the window will just come out - do it when the frame is cool or its very hard to get out/in.
Measure and cut the new rubber - noting how it is slit in the corners, lubricate the channel (before you put the window back) and the non-window side of the rubber with silicon grease and slide in. I did the top first.
The rubber may try to escape so best to use silicon grease, which I am told dries rather than oil which does not!
Time taken the first time about 2 hours. Stuff required - tin snips, silicon grease, vacuum cleaner and something to clean up the channel.
I thought it would take me all day!
Good luck or well done if you have already done it.

Thanks for the detailed info .  I replaced it  a few days ago  .i  just did bottom section  and up  one  side .  took about  1/2 hr  .  £13  incl del from  autosleeper,  thanks again  and  have a great summer
