I don't intentionally take my Vette out in bad weather, so the top is usually down. But of course, sometimes you get caught out. When I put the top up and close the windows, in heavy rain I can get a leak at the top of the windows - this also happens at the local friendly hand car wash. It looks as though what I need to do is not only raise the glass by about 1/8", but also make it come in a bit further so that it makes better contact with the top weatherstrip, giving a better seal.

Can anybody tell me where the relevant adjustment points are, or point me in the right direction if there's a "how to" video posted anywhere?

Thanks in advance,
