Default Dual AFB air cleaner

I currently have two small air cleaners on the dual AFB's on my Hemi. I would like to replace them with one cleaner but haven't be able to find one with the mounting hole lined up with the carbs. It needs to be less than 2" high to clear under the hood. Anyone have any idea?

I would look into original or reproduction Mopar non-shaker units. After that, I would look at factory/reproduction Ford and Buick dual 4bbl cleaners from that era. The one on the GS Riviera's from '65 might work. Or one from an R-code Galaxie or Marauder from '63-'66....You could also fabricate a base plate and use a generic oval filter and cover from a speed shop. Pretty simple to do, out of aluminum, sheet steel, or even fiberglass.

The two critical factors are the spacing between the carb wing nut studs and the hood clearance - almost all the other 60s muscle cars had more clearance than a C1 or C2 or else they had optional hoods. If the stud spacing matches a C1 dual quad (say a 61) air cleaner lid that would already have the height factored in, but I doubt you'll be that lucky..

Exactly right Frankie, that's why I have those rubbers around the nut that holds the stud. Fabricating something maybe the solution.

Had that issue with my air cleaner on my '67 Chevelle so I got one of these:

Not cheap if you need two but it makes the air cleaner nut a "flush mount" and buys you another 3/4" or more - you might have to enlarge the hole in your air cleaner lid if you use them though..

Worst case - you could use these and stay with what you have - it's not bad looking IMO.

You might like the final look and if not the quick latch can be transferred to whatever new arrangement you come up with..

I actually bought a dual cleaner but when I got it the spacing between the carbs for the mount holes was wrong and wouldn't work.

Where did you get those low profile air cleaners?

The trick is getting the base sized for an old AFB:

You can also use a long round headed slot or Phillips screw instead of the stud to mount the air cleaners if you need as much clearance as possible. You can secure the lid properly, and the look is clean. Be careful installing them, though, as you don't want to cross-thread the carbs!
