This trim is probably the frame that goes around the screen that the rubber moulding then clips into 
It's called the trim seat, and now comes in four parts, top, bottom and two sides 
If you pull the rubber trim away from the screen, you see it underneath 
£40 sounds alot for a pattern set. All four parts from VX were £60, with discount, they fit perfectly as you'd expect
allow a week though, as three pieces are in stock in the UK, but the drivers side pillar one is somewhere in euroland
the rubber trims are £50 from VX and should be next day :
oh right thanks for that, bit daft saying you may need them when the window is out, thats with autowindows. there was one omega windows £130 with them, autowindows want £130 for the window + £40 for the inner trim. but omega windows only have green tint one's in and mine is blue. dont like the idear of green on a blue mig.
The trim seats and the rubber trim all get fitted to the glass before it gets fitted to the car

they might need them if the old ones are distorted, or damaged when removing them, hence not knowing until the screen is out
