John and All: The correct part number for a non-AC, non-Hi Altitude 300F radiator is 1903 356. The hi alt is 357 and the AC is 358. The 2099 908 core number is assigned to the 1962 Chrysler New Yorker and Imperial without AC, according to my parts book. The non-AC 300F radiator has the number embossed in a separate piece of metal which is then soldered in a flat slightly depressed formation on the top tank. Hope this helps. 300ly, Gil Cunningham In a message dated 7/13/2011 2:15:53 P.M.
