Hey there...I know someone out there has found out this info...but the 64 65 dated san jose radiors are marked on the top tank.. W MO 2 65 for example.. and are stamped with C4ZE with a letter number config..I have seen U2 Y2 Z2 N2 ..etc..all a letter of the alphabet with the number 2..at first I thought they designated 6 an 8 cylinder and automatic..but just so many variations of those stampings...anyone have a definitive on that or can correlate there radiator markings with there car somehow???
THanks
