Mick, Harrisons have had the pinchweld with rubber seal made and I saw some in black yesterday when I was down there. The rubber seal is very good and easily flattens against the pinchweld so I can't see it causing any problems with closing the window. Paul said it was $13 per metre and that 4 metres was required to do the two rear quarter hatchback windows.

It was apparently an exact copy of a Nos one he has but I didn't take a lot of notice of the pinchweld pattern. Might be worth getting some and trying it before you proceed with yours. Paul told me his rubbers were being made by Bridgestone.
