On the clutch, not sure of the intended use of your 40, but the truck clutch and pressure plate is not the best combination to use. The larger (and heavier) the clutch assembly the slower the acceleration, no advantage unless you are carrying heavy loads or towing. For me a 9 inch clutch would be the best and a 10 inch as the maximum. Getting a flywheel redrilled is not too big an issue and the clutch plate only has to match the splines on the transmission.
