I got it from the local auto parts store.. They have a section where they have replacement oil pan bolts, gaskets, etc..

The first time I went there, I asked the parts guy for some help as I couldn't find any at all and he found me a plug that didn't have the internal nut.. So, he went to his parts drawer and picked out a large nut and threw in the rubber O ring...

After 'fixing' the leak the first time with "Lowes" hardware, using the same plug and finding that it still leaked...... I went back to the auto parts store and while looking for some replacement oil plug gaskets, I came upon the 'proper' plug that had the necessary hardware included.. Which was the inside nut and two plastic washers... It still uses a rubber O ring for the drain plug part, but I grabbed a regular washer that I could use for that... (not going to use a rubber O ring anymore!).

Well, after I got home and looked at it, there was enough room for the lock washer on the inside, so I put that on and tightened it up... So far so good! At least this bolt threads on right.. The old one never did, as the threads were different from the nut...

Anyway, we'll see how this week goes!
