I'd check the frame well by poking it with a screw driver. Otherwise, sounds like a reasonable purchase to me. That's going to have an SR-4 tranny, which is renouned for its weekness, but will be OK behind the 4 banger, which is a good motor for wheeling, but not so much on the highway. The 80 has the short shaft D300, which is a slight improvement on an already good unit.
