Drive Shaft Nuts

professor nailed it. take the whole treasure chest man, you never know what you're going to find under there.

i'd leave the driveshaft in it and just strap it up that way you don't even have to worry about containing the trans fluid.

take a floor jack with you and a pair of stands so you can shimmy shake under there to get at it without becoming a pancake. my friend Justin Case always says take a spare for the car and one for the dolly.
