    What does the dist well plug look like? Can not find a picture in the Avanti parts book, only a p/n

    I don't know what it looks like in an Avanti but this is what it looks like in a 259. You can just see it down the distributor housing. It is in behind the outer expansion plug. They are a 1/2" pipe plug with a hex insert.

      Was Studebaker the only company to use these kind of plugs?

        Those kind of plugs are not uncommon; but I believe Studebaker was the only company that built an engine with a plug inside the distributor silo.
        That's why rebuilders unfamiliar with Studebaker will often remove the plug before cooking the block, and then forget to put it back in.

          I have asked this before but don't remember the answer. Why is that hole and plug there? What purpose does it serve or why was it necessary?

            So Production could drill end to end and so the passage can be cleaned when rebuilding.
