Rear Differential Fill Plug Issue - FIXED

Hammer and a chisel. Make a place and try to tap it loose. I have a front one same thing. I ordered from Yotas but I may just make an attachment and evacuate it through a hose and refill for now. I was going to try a rear plug up front but I don't think bolt head shoulders will clear differential assess bolts for a socket. I bought a wrench and it stripped first try. I have a Matco impact for a hammer I am going to try and loosen it with before I get crazy or lazy. I don't understand why so tight and aluminum but all can be drilled for easy out. I heated it some and nothing.

 

Skid plate bolts plate after 10 minute oil change. Impact can get you in trouble on Toyota for lack of attention.
