NOS ..... I found some NOS gaskets , don't know for sure if they are metal or composite and the bore is one step up to a 3.91 bore . waiting to here back for these people.
Just make sure they are steel and not composite. Make sure they mic them for thickness. Make sure they measure the bore size. Make sure you get photos. Make sure they are in fact NOS and not used. (there should be a package or Mopar Parts tag.
