Hood's hinge's are different, 71 has plate's in the hood that are threaded for adjustment, 72 has slotted hinges, 71 has SMC fiberglass front fender end cap's, 72 has pot metal. Trunk lids are different, 71 didn't have the rib in the center until late in the year, all 72's have the ribbed trunk lid.
