Air cleaner o-ring question

[hallcofish]

Hi. I am looking for the size of the o-ring needed for the nipple on the bottom side of the air cleaner on my 1984 300D. I can't seem to find any schematic showing that o-ring?? Can anyone help me with that info? Thanks

Why not take the bottom of the air cleaner with you to the parts store and fit the best size O ring to the nipple.
