Any know how to remove the outer drivers door window felt with the chrome bead on a 69 Firebird without damaging it? And does this need to be removed to be able to remove glass? A short while back I had to purchase the Dynacorn 1076FX, drivers door glass with tracks and all hardware included. Now come to find out when rolled up all the way it is top of glass is short by 5/16 inch. Any body ever have experience with complete set like this, glass with hardware. HELP. Thanks. Jerry
