Remove the gas tank with the filler neck attached, it should slide out of the grommet. Then just roll the grommet out of the cab. For the fuel line, once it is loosened from the tank sending unit, go under the cab and remove the rubber hose that connects it to the line on the frame. Then remove the rubber grommet in the floor and feel the line up thru the hole. The alternator bolt is 3/8"-16 thread, but I don't know the length. You should be able to measure and get close on that.
