I'm seriously thinking about doing a 1pc window in my IH.. biggest reason is new vent window gaskets are over $400..I read horror stories about the gaskets poor fit, leaky windows,etc etc
So I contacted balls vintage glass, and I can get their 1 pc power window conversion kit that comes with everything needed for just over $500..
