I'm NOT obsessive! and they ARE out to get us!

Ok, this is what solved the problem well enough for me to get back to the border in a precautionary bailout from my trip.
It held the (replacement) oil in and didn't fall out.
What more could I ask?

This is my 'solution' after 400$ for a 3 day trip to Saltillo NL Mexico and back.
Oh, and 300$ for new bearings and seals and 'guidance', plus half a day in the parts washer, and a day on the bench.
The neutral switch only gets changed with the transmission out, and the transmission drain plug is accessible enough to wire during any fluid change.
Now my motto (at least for drain plugs) is "What, me worry?"

Yes, I'm going to do the Engine Oil Drain Plug too. And then maybe the final drive and drive shaft.
