Can anybody tell me what the part number is for the seal/weatherstrip that the door windows seal up against when you shut the doors? Is it 20674282/20674283??? Thanks for the help.
The numbers you have are for the belt molding with seal that are horizontal on top of the door.
The roof rail weatherstrip that runs up the "A" pillar, across the roof and down the "B" pillar for a hard top cars are 20737658 RH and 20737659 LH
They are still GM available, GM Parts Direct around $103.00 ea plus ship. T-Top cars are a different part number.
Thanks for your help Phil, those are the ones I needed to know about.
