Welcome thebigk,
Most any air cleaner made for the single barrel carbs will work. Measure the neck on your carb just to make sure. They are pretty easy to come by and not expensive. Mine attaches by clamping on. The clamp is part of the air cleaner. I don't know about your year truck but in the 57-59 years the 3/4 ton does not share the same hubcaps with the 1/2 ton. My guess is that is probably the case the 1955 models too, but I don't know for sure.
