I'm fixing the window on the Capri - the glass had come out of the mechanism. Straight forward enough - lever out the perished rubber int he mechanism steel channel. Remove channel from door and treat rust, paint and refit. Trial fit of glass showed why it had come out - the rubber seals are rock hard - The baily channel is hard, waist seals like rock. So where can I get replacements? Clarke rubber used to keep some of this stuff - will their baily channel work?
While I'm at it - do people use the premade door seals or pinchweld?

Clarke Rubber have a few options for the bailey channel, just take your old bailey channel in and size it up. For the weather strip if you need them you'll probably need to go to a specialist auto rubber supply place. I got pre-cut weather strips from Bill Thompson Auto Rubber in Bayswater (Melbourne) for MK2 Escort RS. Not sure what is the go with Capri's but I used pre-made door seals with moulded corners on my RS but this was still pinch weld that needed to be cut to length anyway.
