lol, I see I have 2 usernames?, must have created an account and then forgot and created a new one. Anyway, if you are looking for openable ventilation windows, I might be able to help you. Someone I know actually offered a set to me recently. I don't know what he wants for them yet but if you're interested I can inquire. It is someone in NL. Otherwise send me an email on the subject.
It runs smooth (even upside down ;-) ) Can't wait till my car is far enough to actually have a running engine :D
