Everyone: keep in mind all 1953 & on Stude. chassis part #'s and casting #'s 
start with 53: early and 15: late, AND it is quite hard to read. The casting
 # is raised numbers on the second counterweight (number one rod journal-rear 
counterweight) cast on a curved surface so the first or last # may be
 unreadable or close to it!
