I just dropped my pan. Twice actually. 19x 10mm bolts and just wiggle it around your exhaust and crossmember to get it down. My dipstick tube came right apart, so before you do anything else just see if it will separate.

Be careful if you have to pry the pan off, the aluminum is really soft and you can easily gouge it with something like a screwdriver. If you strip a bolt, use heli-coils to fix it. You can do it without dropping the pan. So say you have 18 of the bolts tightened and the last one strips, you can fix it without taking the pan back off.

Felpro gaskets are usually good, but I was unimpressed with their AW4 gasket. Lubelocker is the way to go IMHO.

Good luck!
