I've been agonizing about replacing the clutch on my truck for weeks. Anyway, I took it to a friend's place who has a lift. He's a truck mechanic part time so he knows his stuff. He had a great little trick that saved a ton of time. In the manuals it says you have to disconnect the exhaust and remove the transmission from the truck. You can actually just loosen the transmission, turn it sideways towards the driver's side, then push it back. It'll fit on its side over the middle cross member. Then you can run a strap under the front of the transmission and that will hold the front of it up. That way you just put on your new clutch, throwout and pilot bearings and other stuff and put it back together.
You also don't have to disconnect the exhaust. Just wedge some chunks of wood under the oil pan on top of the second cross member and it'll just sit there. The exhaust will hold it steady.
It took us 2 hours to do the whole job. Not bad
