6 bolt wheel pattern size and 5 bolt sizes

[russellrox]

I am wondering what are the wheel bolt sizes as in 6x5.5 or whatever it may be, also what bolt size (pattern) is a 73-87 chevy truck with a 5 bolt, I am considering converting to a 5 bolt, but not sure yet. I am just looking to keep my wheel choice options open in case something cool comes up. What stock wheels will fit these trucks in 6 bolt that bolt right onto a 63 c10, I would love to find a set of turbines but not sure if it's possible.
