What a pain in the ass. I spent a couple hours struggling to get the ribs into the left tank. The nose of the ribs did not want to get all the way in without a lot of persuasion. It looked like the skins may have been bent to far at the factory and were causing the ribs to be pinched before they could drop all the way in. For the right tank I decided to bend back the skins a little bit. This made all the difference in the world. Everything lined up perfectly and it only took me 20 minutes to cleco the right ribs in fully.
Left tank is ready to go. Right needs to be drilled yet.
