Stuart's just messin' with ya a bit. The M/C is under the floor boards. If you lift up the floor mat, you'll see a plug, about 3" in diameter. That is the filler access hole to get to the filler plug on the M/C. The M/C itself is bolted under the cab, to the frame. It's held on by 2 bolts. The pedal arm does have to be removed to get the M/C off. Depending on the condition of the one you have, you migh go ahead and get a price on a replacement M/C as well, just in case you're is too far gone to rebuild.
