81 Stock Radiator

My radiator started to leak. As I had it out to fix the leak, I wanted to buy new seals. I discovered that the radiator core is 1 1/2" instead of 2" or 2 5/8" . What is the stock size for a 1981 with AC.

Thanks. When its specified a 2" or 2 5/8" are they talking about the corre thickness or thickness of the end caps. Where is the two inches measured?

thanks for getting back to me

1.58" is the standard radiator with and without AC. The optional HD radiator is 2.68". Both numbers refer to the core.

The tank measures 2.58"
The core looks to be close to 2"
