my 78 6 wheel the previous owner ran tracks couple tome with too much air in tires(4 psi,20 inch runnamucks) and the underside is scuffed up,couple rivits around muffler box ground right off.also some cutting into side of tub up front,about halfway through the plastic.spacers prob.would have prevented all,if not at least wearing into the side of the body.your 82 may have more clearance above the tires,watch closely!HTH
