Part # 201555 is NOT in the 1949 Illustrated Parts Book. The 1948 illustrated book lists the item for 1947-48 Kaisers, all models. The Frazer version is chrome plated and has a different part number.
This is an example of what I have repeatedly said about support materials...you need to have the parts book for your car along with the factory shop manual (except for 1954-55 Kaisers and the Kaiser-Darrin: a regular shop manual for these cars never existed, just service bulletins and use of other existing K-F service manuals in combination).
