[422 SS]

I bought a 2003 3500 Express cargo van last week.Well I was doing my normal new ride look around and noticed something really interesting.While lying under the truck looking at the axle and whatnot I noticed a Dana emblem stamped on the diff cover.After looking at the sticker on the axle tube it said Dana 70S.When did GM starting using Dana axles again.It is stamped on the pumpkin also.Anyone know anything about this.

You know, I remember every so often I would see a 1988-89 C/K truck with a Dana 70.
