Time to re-new the front door seals on my 74 40. I bought a right and left side OEM weatherstrip from Cruiser Corps and have the old weatherstripping off and all the residue off (combination of goof off and wire wheel on the drill). Now, the OEM stripping has a flat side and a c-shaped side (sort of a channel I guess). What is the correct way to mount the stripping? Does the flat side go down with the channel facing out of vise versa? Does it fit in the corner where the 90 degree angle is? Any good threads on this? I found one thread on a door refresh using the CCOT stripping, but it doesn't really say which way to apply the weather stripping.
