2 barrel air cleaner base (and cover)

If you could find a database that listed air filter element diameters and heights, you could probably find one that would drop the height just enough. For instance, Fram discontinued the proper Commando air filter, but I found a Buick element that fit the housing and was maybe a 1/4 inch shorter. Then I figured out that Wix and NAPA still had the correct element.

Oh, BTW, Alan, last week I swapped the little stud bracket on top the carb for one with a shorter stud. The old stud stuck up well above the cover lid. It was the stud on the original (?) Holley that cut the rip in the hood pad (I suspect the Holley was a replacement for another carb that behaved just as badly — my dad and several mechanics chased the stalling problem for years with no success). I cut it down shorter after I got it. The 1bbl is a different bracket though you could probably make them interchange by bending the wires enough.
