There were two different manufacturers plates used. The early one is part no. 105196 and has a GVW of 3180, 1244 front and 1936 rear. The later one is part no. 110573 and has a GVW of 3244, 1286 front and 1958 rear. Where is the cutoff? I haven't discovered that yet, though I would imagine it to be at the 81/82 model year. All the 82/83's I have seen have the later, while all the 81's I have seen have the early one. Why the change of 64 pounds?
