It's a 2wd 1-ton. Thanks for the info. I don't have a NV4500 in my possesion yet. I knew there was a difference, just couldn't remember what it was. I do know where there is a NV4500 from a Chevy local to me for $200. Pilot bushing is the same? Any tips or info for the hydraulic clutch set-up? The mounts on the frame rails? I'm diving into new territory....any help is appreciated. GM is always coarse 10 spline, correct?
