Some m1028s also came with an np205, I have seen a few this way. I am pretty sure they have the same size spring packs as well, I know my m1008 has a massive set of leaf springs in the back, with atleast 10 or so leafs. So I would imagine that the front lim. slip, and possibly the t-case is the only difference. They are both also definitely one ton as well...d60 vs d60. Now there were some light duty m1008s that slipped out of the factory with 3/4 ton running gear, but from what I have seen, they are far and few between.
