Correct lug nuts

[Karguy]

I recently acquired a total of 20 NOS C5ZZ-1012-B Ford service replacement chrome lug nuts. I have what I believe to be several of 6S281's Original Lugnuts used on its Kelsey Hayes steel wheels. The overall Length of the old one is 1 3/8", the service replacement is 1 3/16".  Does anyone have a known original that you could measure for me please?
Thanks, Karl

Perfect example of do your homework before you purchase parts on eBay. Curious, anyone know what the application is for the C5ZZ-1012-B shorter lug nuts?

 Absolutely, there have been very few of these learning experiences thus far.

C5ZZ  lugs are for 65-67 styled steel wheels
