A potential problem with Super Sixing my 1973 Duster.

Your 1bbl. air cleaner isn't going to fit the Super 6's carb anyways, so you'll need the air cleaner too- it should already be clearanced for the AC compressor. And like everybody has already said, grab ALL the throttle and kickdown linkages- and take pictures of how it is ALL mounted BEFORE you tear it off so you can see how to reinstall it all!
And make sure you take pictures and/or make notes of how all the vacuum hoses are routed and what they're connected to- you may need to grab a couple of extra fittings or gizmos that you hadn't thought about. It'll save you a return trip to the boneyard.
