Harrison Radiator Question

[1969L78Nova]

For what its worth the markings on my 1969 L78 Nova (4 speed) Harrison radiator are: "O" "M"(recessed)"O" . I therefore doubt the "M" designates a date code. Looking forward to other responses as to what these codes mean!

There may be a letter or two that wasn't used.

Check out this link from the same subject over at the Team Camero website. Does anyone know about the other tag that was found?

M is December for half of GM parts. What's the date of your car?

On that tag, didn't realize it was in the airflow. I think rebuild......

Its a March 69 built car.

Does your "M" look like the "E" that is posted? It would be correct for a March built Car.

It's definitely an "M"

Over at the Team Camaro site it was brought up that the application tag also has the letters of the tanks.

Does anyone have the information on all the application tags that includes the letters of the tanks to verify this?

As for the date coding, are both tanks date coded or just the fill tank?

here is a picture of some Harrisons. The top one has a tag with the tank letters in small size but different letters in big case. I notice the location of overflow tube differs as well as diameter of rad outlet.

One question, do you know for certain if your radiator or tanks are the original units?

If "A" is for January, that would be a correct radiator for that car.
