I got 3 2.5 ton GM axle. 2 rear and one front. Looking to get $800 for all three. Also have front and rear axle from a '66 chevy. I dont know much about them from what I am told they are manufactured by napco. THe rear look like a lot bigger version of a 9" with a removable diff and removable cover on the rear. The front is a massive diff and closed knuckle. I am told they either came with 5:13 gears or 4:56. I would like to get $400 for front and rear.
