I found a video online that outlines the swap from the weak 8.6 10 bolt to a semifloating 14 bolt from a 88-98 heavy half, and had one found but the truck disappeared. So my question is this: has anyone tried to fit an axle from a 2011 half ton in place of the weak 8.6? It's going into a 2002 yukon with the coil spring suspension so I'll be replacing spring perches more than likely I'm wondering about width. I have one such rear-end in my possession with only 40,000 miles on it. 373 posi. Same ratio I need. I hope it's not an 8.6 too.... Please help!
