The standard clutch for pass and PU is 9 1/8". Of course the truck could have the optional 11" clutch.
The flywheels are the same size.

If you have the front fenders off you could leave the trans in place.

Six months is not that long for a engine to sit. I have pulled engines apart that have sat for many years and the bearings were still full of oil. If moisture has gotten to the engine I would put a little oil in the cylinders through the spark plug holes.
