Parts manual has 3 part numbers for 51-4 pumps. One for 51-52 regular use, one for 52-54 regular and PS cars and the third for 53-54 AC cars. I believe the difference is the hub depth. I doubt you will find written specs on what each is but if no one can measure theirs you might PM James or call the Packard guys at Kanter and see if someone would measure a 52-54 PS version 443424 pump for you.
