SBC 350 Water pump pulley: What size bolts?

Hi Everyone,

What size are the threads for the water pump pulley? I need to buy some new bolts, and I want to make sure I get the correct size and thread. Are they 5/16-24? It's a short water pump, stock style, on a 350 sbc in my 67 C10. Does anyone know? Thanks for any help.

How was the install on the Vintage Air? Any challenging (more than normal) issues? I am getting ready to purchase an A/C System as well and would like your opinion.
