Been studying the Scott's Old Auto Rubber catalog looking for weatherstripping that could replace the cracked and leaking stripping on my '73 504 GL. The stripping comes in two pieces, one that wraps around the front and sides of the roof and is very similar if not identical to the 220.005 quarter vent seal in the catalog. The back piece however has me stumped, the profile looks like quarter vent with very long overhang and slight dip at the end. Anyone tacked this problem?
