80mm on a 71

Have a 71 with some engine mods(deletions by PO), no air pump, and the rear connection to it on the air cleaner was just left open,(which left intake of a small amount of unfiltered air). And the air check valve outlet was plugged off. Ran ok, but was wondering if I could connect the air check outlet to the back of the air cleaner?

But if there is,something left good to weld to, should the new go over or under?

Hello, First time posting, now have my 71 in the garage next to my house so I can spend countless hours and $ on it this summer. My first question, my floor pans are rotted gone, I have a lot of 18ga cold rolled sheet steel and will use that instead of buying a pre made pair, and use some 16ga rectangle steel for the floor supports, to save some $. Is there a hard and fast RULE, should the new pans go over or under?
