    Its the size that fits past the threads but not the head. That is the one I believe works best.:D

    Wow, we are a bunch of comideans! But if it helps...

    We know the head of the drain bolt is 13mm (Actually it is NOT, it's a 1/2" = 12.7mm, because Chrysler design), and we have a semi disturbing picture of where Nathan keeps his drain plug.

    So with that, the warsher should be around 11mm ~ 7/16... ;)

    I use a magnetic drain plug (never know when I'll have to check my roof for aluminum). I carried the drain plug into the parts store & the nice guy behind the counter said "is 15 enough Chuck?" Yep it was & is.

    Scott if I remember correctly the drain plug is 14mm.

    Thanks MF.......

    I think I remember where I put the OEM plug, it's buried in a box after my last garage clean-up/organizing campaign.

    And MCS02.....I have the OEM oil temp plug which replaced the regular plug, and it has a standard washer instead of the built in rubber one.

    Scott I just buy them a 1/2 dozen at a time at the dealer when I pick up oil filters.

    No local dealer.

    And I forgot to add that I have the oil temp sending unit drain plug.....so no rubber washer. I like to change out the washer at each oil change.

    If you can't find it how are you keeping the oil in? Wait I know 50w and duct tape.:D

    Have you looked to see if it's screwed into the oil pan? That's where I keep mine.
