Jordain, I'm interested to see what you've got. Would be great if I can make these work. Have put a lot of work into the body and getting a good seal will be important in keeping it that way.
With regard to the rear flipper windows (ie the ones that attach to the B pillar) - I bought these from Phil. The fit well, with exception to what some say, they pucker out as the round the joint at the C pillar lower end. But now that I have fitted them, its possible you are meant to "mitre" that joint. One of the Malay or Thai manufactures (which I dare say are the same moulding as Phil's) suggests that you mitre the joint...
