I have a chance to pick up a cab, blower, weights and chains

A guy 3.5 hrs from me has a cab, snowblower, weights, and chains for sale. His is a Sierra 1648H, I have a Grand Sierra 2200. I would really like the soft cab for my Grand Sierra. Does anybody know if it will fit? I can't seem to find much on the Sierra 1648H. The price is right, but it's a long drive if the stuff isn't compatible with my machine. I already have a blower, weights and chains, so the real draw is the cab.
