98 Cont. Oil Pan and Shaking in front end pass side

[1998 Lincoln Continental 4.6L V8, 129000 MILES]
I was driving my car last ight in a dirt parking lot and I rode over a stump, which ended up puncturing my oil pan, but left everything else unaffected. I parked my car again, to prevent any further damage to the engine. I have been searching all over the internet and cannot find any place that sells the oil pan. I have found the oil pan gasket, bolts, everything but the pan itself. Also, I was wondering, as a tempory fix can I use JB WELD to patch the hole until I can get the oil pan (if I can find one). How do I go about fixing this. Both temporarily and permanently.

Second question,
What could be causing the shaking on the front passenger side of my car. The wheels have been aligned, and the tires rotated. The bushings and tie rods have already been replaced. What can be the problem? It seems to shake the most at around 30-35 miles per hour, but shakes less around 65-75 mph. Oh, the tires are also fine.

Any help greatly appreciated.
