well no.1 the door seal - mk2s have a different seal - looks a bit better design, im actually after one myself for the drivers door

but i do have a copy of the profile of the mk1 one and ive probly got a mk2 one somewhere - just not in perfect condition, but good enough to get a sample off
no.2 is shown as a short strip but it actually goes all the way round the window and back down the channel
no.3 (inside one) is a rubbing strip on the mk1's in not sure what it is on the mk2's

but it doesnt look like the outer one is listed -just the pic
no.4 i assume is the clip to hold it on
where abouts are you? are you UK based?
