I´m looking for a new radiator for my M38. Now the question, is the radiator/cooler the same as in a Willys MB, CJ-2A etc. or do I need a extra radiator for the M38/CJ-3A?
They are different. There's only one M38 radiator and it has the rod brackets down low on each side, the M38 specific fan shroud and the lower bolt setup.. The CJ2A and early 3A use another radiator. And the later CJ3A uses another again.
