Did this while removing the oem radius arm brackets on my 2016 6.7. Got a little over zealous with the air hammer and when one of the vertical rivets finally let lose the tip of the hammer bit impaled the fuel cooler.

Anything to watch out for when making the swap? Looks fairly straight forward.

PS - Removing the 14 1/2" rivets holding on the radius arm brackets was a real treat. I will never be doing that again..
