if you were to get the drain plug bolt out.
the treaded part of the drain would be loose and fall down into the drain pan, if so you do not want this part flowing around down in your oil pan,
even it you are able to replace the drain with some other type drain bolt.
I would be concern about the threaded part of the old drain and where is it.
maybe i am just to cautious,
good luck, but not worth ruining a good motor over a drain plug.
