Re: pulley bolts
They are 3/8-24 threads on the crank.
Length is completely dependent on what pulleys you have. Some lower pulleys are steel and some are cast iron. They take different lengths. Water pump pulleys are 1/4-28 thread. Again, length depends on the particular pulley you have.

Re: pulley bolts
There are different stock pulleys. I have them hanging on my shop walls. Some pulleys are thicker and some thinner. Some cast iron, some stamped steel.
