Radiator Tank Codes 1969

[Pacecar]

Restoring a 1969 big block automatic with Turbo 400. I looked at the tank codes listed and did not see my code. The passenger side tank is stamped SB with a date code C. No codes on the driver side tank that I could see. It is a Harrison radiator. Any ideas what the SB code is ? has the correct brackets.  Thanks
