I have two air cleaners for my 54 Canadian gmc and both had no wing nuts on top .I was wondering if anyone knows if there is a special top nut .The pin that comes up for the top to go through has a point on both so they don’t look like they were messed with .The reason I ask this is because there doesn’t seem to be enough to screw a wing nut on as the pin only sticks out about a quarter of a inch .I was thinking of drilling a hole in a 5/16 bolt and threading it so they have more threads to hold down the top.
My air cleaner has a little knurled nut on it that has a little more reach than a wing nut. It has a narrow part that goes in the hole. Not sure if it's stock, though. It was like that when I got it.
You might replace the threaded rod with a slightly longer one.

How about getting a longer piece of threaded rod to replace the short rod ? Kinda like if one wanted to replace their air filter with a thicker one. Odds are they would need a longer center rod.

Here you go. LINK They also have them with a solid top.

Could do that also but the rod is welded further down but I will take another look to see which is easier. There must have been a similar nut like Otto has on his .
My oil bath unit is original to the truck as far as I can tell, the threaded rod is slightly adjustable at the carburetor bracket and can be unscrewed to allow it to protrude from the top of the air cleaner, a normal wing nut is all that is required for mine.

I'd suggest using a coupling nut, and grind about a 1/2" long shoulder on it to center the hole in the top. Maybe use a flat washer to spread the load out across a wider area. Then you could either weld/braze a couple of wings onto it, or just use a wrench to tighten it.

Cut your rod off short enough to clear the top after screwing on a coupler. Thread a bit further if you need to. Use a piece of threaded rod to extend the amount you need for your wing nut…
