That totally sucks! I can't speak for everyone else, but I do that kind of stuff all the time.
Two weeks ago I dropped my axle housing off one of the jackstands. Luckily, I narrowly missed bashing my pinion, or I might have had to replace the outer bearing. I did however manage to pinch my air hose, and it bubbled up. I forgot about it that night, and the next morning, I was on my way out of the house, and I remembered the bubble, so I turned the compressor off. Good thing too because the hose ruptured and drained the tank, and the duty cycle is %50 so it would've destroyed my compressor. Almost a HUGE mistake!
I'm looking for a Scout II Dana 300. Drop me a line if you have any leads. Thanks
