Here is a used widow seal Mopar part no 2893 442 which I have found to be for the left door. For a 2-Door plus would also fit a Convertible which is also a 2-door!! It is in great shape, the rubber is soft. A metal base is in the part too.

Have fiting C-body 's 1969 to 1973.

Dodge Monaco + Polara

Plymouth Fury I, II , III +VIP

Chrysler New Port and New Yorker . Please double check fitment,  as always.

Please feel free to ask any questions. Or leave a reasonable offer or bid. Take care!!
