Had my 70 radiator recored three years back, in a Stockton, Ca., radiator shop. Had the option of a three row core for 20.00 more than the std 2 row; so went with that. Cost was $285. Just NOW registered on here. My 70 is a daily driver in resto mode with a few small things left to get it to "like new" mechanical performance and reliability. Will post pics soon.
