1984 gmc k3500 has a Dana 60 front with a spartan locker and a 14 bolt rear with a grizzly locker. 350 small block and sm465 4 speed trans. 5 40/13.50r20 maxxis razr mt tires put on last fall 4 have about 500 miles on the and one new spare. The body is pretty rough but the truck runs good and goes really well off-road. I might be willing to trade for a nice fuel injected dual sport bike like a crf300l Klx 300 or a tw200.
