Is there a difference

The 63-65 crank washers are close to the 66-67 style but are off by about a 1/16". The later 68 and up style is same diameter as the 66/67 but a totally different shape and much thicker. Here are some pictures from my crank adventure from a few weeks ago. Doubt anyone would notice the early difference except an anal OE Gold judge. Or it could just be a plant variation. Cranks go 65 original washer, 66 original washer, 66 later washer and 68 up original washer.
