I have a 1984 300d turbo and I am having door issues.
The door striker on the back right door doesn't really allow the door to shut consistently. This is because the black plastic piece that goes in the door striker is missing/broken. I cannot buy just the piece, I have to buy the striker, but when I look in the catalog, there are only front door strikers ( http://catalog.worldpac.com/mercedesshop/sophio/wizard.jsp?partner=mercedesshop&clientid=catalog.mercedesshop&baseurl=http://catalog.peachparts.com/&cookieid=21V134X8621V148UN4&year=1984&make=MB&model=300-DT-001&category=All&part=Door+Striker ).

Are the door strikers interchangeable between the front and the rear on this car?

Bump!

Front and rear appear to be the same. 123 720 01 04 left, 123 720 02 04 right.
