Rear Diff Plug HELP

[Diastole]

Thanks for all the help.
Yes the plug removal process went smoothly, following y'all's advice. Attached are some final pics for those who have messaged and posted.

Yes I am in a club (a great one, with awesome resources), and I went to them first:
1) check with Ford Barn
2) email the MAFCA technical director
3) I am not sure
4) sounds like you got a great plan

I had a set of NPT taps. I ran them in and boom! no resistance and no chips. Threads were fine.
The Snyder's plug screwed right in with teflon tape.
No leaks after running her for about 10 miles.
