I have a a reproduction fiberglass fresh air, air cleaner assembly for 70 and up B-Body Mopars. There is a repair needed to the air cleaner base hole. I believe this was the raised air cleaner base and someone cut it off to lower it and thus instead of a 5 1/8" hole it is about a 1/4" to large. My plan was to fiberglass for a quick repair. I was going to use this on my Dart but my scoop is located wrong for this to fit. There are two lids in the picture. The round lid is for a 14" air filter element, the other lid is a Hemi lid and a six pack element will work with it. You will need to fab a bracket for it. I installed this same set up on a 69 Baracuda with a six pack hood and Hemi lid. It looked and worked great. $225.00
