My book shows for 1951-52, casting number 5453781 as a 1 3/8" wheel cylinder with a part number of 5453780. Im gonna look through some of my other manuals as it doesnt show whether it has hucks for the front or bendix. The picture it shows of the fronts are all huck style for the bigger trucks while the rear shows 2 cylinders for each side with bendix type.
