After a second look at my other pictures, Yes first pic is a 72 C60 and it has the 67-68 "custom" door badges. Took a look thorugh a few more pictures I have and here is a C40 (not sure on the year) that looks to have the appearance group but no door badges. all the fender emblems I have ever seen are just the different years of C40, C50, C60, never a "Custom/60" etc.
I have also noticed there are different hood bowties some are flat and some are raised at the top.. (havent figured out if its a year thing or model difference)

The 366 cranks are steel and the same as a 396 and 427 car cranks
