Use plenty of pb blaster and give it plenty of time. Youll need some sort of remval tool to get the stripped plug out.

 

you need that remove tool shown couple of times on Truks @ Power Block @ Spike
you will have to drill a small hole and stick that in and turn gently.
also firts try the fill plug, then the drain plug.
but before, get new ones also.
