Van’s includes some MK-319-BS rivets in the RV8 empennage kit. These require a #33 hole. I wanted a few extra, so ordered CCC-32 rivets from ACS which, according to their website, are equivalent to the MK-319-BS rivets. Not so fast, Grasshopper! I received the ACS rivets today and they are clearly different. They fit into a #40 hole.
So the question is... What am I missing here?
