Does anyone know whether a factory 69, CJ w/AC had a 3 core or 4 core? I belive I have narrowed it down to a 3 core but I’m looking for some back up knowledge. My research indicates any big block with air came equipped with HD cooling and a 3 core radiator. I realize there are 4 row options out there but then fitment becomes an issue, due to thickness.
Thanks in advance,
