Thanks for the information.
A lot of good points were brought up.
I think I am still leaning towards the 10 bolt. I have heard the 8" is easier to repair and service, but I have got some leads to a used 10 bolt. I guess it also comes down to the fact that I would like to keep my Chevy as true to GM as possible. (I just can't give my father in-law the satisfaction of a blue oval part on my truck!)
Thanks to everyone.
