I assume you have a SB ...rather than mess around with all those belts...why don't you consider picking up a late model GM serpentine system at a junk yard. For about $100-200. you can make your life much simpler.(I installed an Old Air in my truck and the serpentine system saved me substantial time and aggravation).
