is the one ton rear end in the 2wd c30's the same as the rear end in the k30's? the pick-a-part by my house has an abundance of 14bff in 2wd pickups. i'm thinking about picking one up and then waiting til i find a good deal on a d60 front end. has anyone ever found a d60 at a pick-a-part type salvage yard? it doesn't seem like they ever have any k30 pickups at this one by my house.
