Pelican Parts sells the front door gasket (weatherstrip) for $169.25 each.
PN 51-71-1-977-727 (driver door) and 51-71-1-977-728 (passenger door).
A trunk gasket is $48.60 each (PN 51-71-8-171-243) for 2 door models.
I'd love to replace my front door gaskets, but at $170 a pop, that's too much just for a piece a rubber. I have a few tears and rips in the door sill area of the gasket that I think I might repair with a bicycle tire patch kit or something along that line. It's nothing you see anyway since the door is closed, but the gasket could get worse if not repaired in some fashion.
