Hi All,
I can't seem to find specs for CCP-42J rivets anywhere. I see that they appear shorter than standard CCP-42, so I assume their grip length is going to be less.

When I bought a used kit, it came with a bunch of hardware. I have two bags of rivets that were labeled as CCP-42, but with one that had CCP-42J as being its actual type. Trying to make sure I use the right rivets in the correct place.
