Thanks all ... I have a 51 GMC suburban. I have everything in place already .... do you all think I can use sealant on the inside of the window channels to "seal" it (sort of like caulking the interior) or do I need to pull them all and seal underneath the channels? I would hate to have to do that, having them in-place and all. I'll check the shop manual.
