In my 1955 Olds parts book it shows 3133684 for '55 non-A/C cars.
In my 1963 Olds parts book, the number shown is 3134195 for non-A/C '55 cars.
Somewhere along the line, the radiator was probably revised and assigned a new part number.
The Hollander, depending on date of publication, mirrors that.

Ok the Hollander I have is 1956. So either P/N is correct easentially. Thanks Charlie. Now Im praying the local radiator shop in Albuquerque knows what they are doing. With all the old school shops closing or closed you never know.
Some additional information on radiators from 1953 thru 1956.
The core less tanks are the same from 1953 thru 1956 regardless of a/c
For 1955 and 1956 the a/c radiators are nearly the same. The a/c radiator only has mounting tabs for the fan shroud used with a/c.
The other difference in the two year models is the oil cooler for the jetaway.. 1956 fits 1955 by ignoring the oil cooler. 1955 fits for 1956 where the jetaway is not involved or by switching the lower tank to include the oil cooler.
1953 will fit newer by drilling new mounting holes for the screws. Newer fits older by drilling new mounting holes for the screws.
Higher pressure radiator cap to help prevent boil overs especially with the a/c option.
Just be sure the heater and radiator have been refreshed to take care of solder fatigue. New hoses as well. And likely new freeze plugs after all these years.

I would really discourage a higher pressure radiator cap. Depending on what kind of heater valve you have, it may cause the Ranco heater valve rubber seals to fail.
I plan on just picking up my old radiator from the shop, they said the header panel is bad so they want a new core. I still may put a core in it, but for now I purchased a replacement from US Radiator to the tune of $800. I will post picks once I get, it should bolt right up, but we will see. I will still just run the correct 6 pound cap, it cooled just fine before the leak.
