What axle came standard under the front of a 4wd '79 3/4 ton chevy truck? It's a 44 not a 60 right? Also what's the difference between a 3/4 ton and a 1 ton 14 bolt? There's a post elseware on the boards stating the spring pad's are narrower and that's it. I was wondering if the spline count is the same and the yoke size is the same.
