Just noticed that the strip that runs up the side of the windscreen, across the roof and down the rear window has gone missing on my MY97 Imprezza Type-R (two door). (off-side)

Must have blown off in the wind this weekend (thought I heard something funny!).

Anyone know:

a) whether I can use the bit from a four door.
b) where I can find one to replace it.

Thanks.

 

......

c) or how I can find out the part number.
