Super Six carb and air cleaner

Looking for either NOS on the carb or one without the bowl warp or throttle shaft slop that I can rebuild to spec. I have super sixed the dart, but the carb that's on it has been monkeyed with so much, it's stuck in fast idle and can't be adjusted as the linkage has been removed from the carb (I dunno, got it like that) and it's high time to do the valve lash adjustment. I'm scared to do it at 800ish rpm! Also on the lookout for a good super six air cleaner, mine is off a 318, and is functional but is pretty worse for wear.

Any and all help is much appreciated!
