Anywho, it's fairly simple and straightforward, if any of you feel like you can get a benefit from this.
So I bought a chrome diff cover on Amazon, because it was slightly cheaper than a stock replacement.

I bought some arbitrary oil drain plug on Amazon, and matching nut's at my local home improvement store,
Then I held it up top the axle and eyeballed the placement of the stock fill plug, and punched a corresponding location on my new bling cover. I flipped it over, made sure that my plug wouldn't interfere with the diff gut's, and busted out my step drill.
Not exactly rocket science, I just went up in steps until the bolt went through lol. Then I used a 36 grit disc and blew the chrome off the backside where I was going to weld.
Ran the bolt into the nut, snugly. You can see this particular bolt has a magnet on it, but it won't be submerged, so it doesn't much matter.
Realized it would probably weld better without the coating lol,
Turned my welder up and burned it the
in there for all eternity, no tacks here, I just went full potato on it, as I really don't want it dropping into the diff on me lol. 
And here is the finished product, my chrome got a little discolored, but whatever, it was super easy to put the gallon of oil in this pig it takes,
