To my way of thinking, a 12 bolt would be the best of all choices, and a 10 bolt a close second. However, I don't know just when GM went to them in the trucks. Since your truck is a C20, the original rear end will probably hold up to a fair amount of oomph; depending on what the first gear ratio of your tranny is, something in the neighborhood of 3.90 or 4.10:1 rear end ratio would be fair.
