Air Cleaner Ideas

I have a 318 in a 70 Dart Swinger that I have freshened up and added an Eddy Intake and 650 Carb. Would like to keep the "stock" look so I want to re-use my stock air cleaner. Obious problem is that the original air cleaner is for a small carter 2 barrell. Was thinking about cutting out the center and welding in a riser, or maybe finding a stock cleaner off a 360 or something and welding the center of that in place, just not shure if a stock 360 4bbl cleaner would even be large enough to fit the Eddy carb. Anybody done this before?
