1. Did the 54 use an oil bath air cleaner?
2. What other years that will fit the 1954. Jeffrey
1. Yes, but the wire-mesh spark-arrestor air cleaner was standard equipment on small trucks
2. Many years through 1959 - any cleaner used on the the same top-diameter carburetor (several styles, depending on size of truck).
1949 through 1959 235, maybe:
