Turquoise = 69 340 pass side valve cover

understood that, should have stated that I was trying to figure out why Chrysler created so many different 340 valve covers and switched oil fill sides.
Just using passenger side for example there are no less than 3 different ones 68-71:
1968 passenger side was red with small tabs, no large wire loom, plug wire grommets on top, opposite side oil fill. 69 is turquoise with small tabs and large loom, opposite side oil fill. 70 and some 71's orange, with small tabs and large wire loom, oil filled side. Later 71's blue with small tabs minus the large loom and I have seen several passenger orange like last one Scott posted less the loom, both oil filled side.
I think 73's are different again with the longer small tabs.
