InterestingÂ…I wonder how many genuine factory-made variants there are under just the three part numbers we're talking about, and how many additional variants caused by not-quite-correct reproduction efforts. It really seems random on a case-by-case basis, doesn't it, whether Chrysler kept one part number despite 25 variations in a part, or applied 25 different part numbers despite no variation in the part, or something in the middle.
