Cant help you if whether or not they all came with the decals. But it seems that when guys repaint, they sometimes dont take the time to put the decals/paint stripes back on. Or it wasnt in their budget. I see most 73 SS cars without the black tail panel. When I bought mine in 82, every 73 SS had the black tail panel and side stripes. But I guess when guys repaint they just paint everything. Or they bought the car with the tail already painted so they think it came that way. Sometimes the finer "details" get overlooked or they just dont like the stripes. Just my 2 cents.
