C8ZE-L, L1, or L2 Radiator

[8T03S1425]

Looking for a correct radiator for my 02/14/1968 build date GT500, 4-spd, with A/C to replace the generic one currently in use.

What is the difference between the L, L1 & L2 suffix designations, and which is most appropriate for my car?

I believe for your 1968 Shelby GT500 with a 4-speed manual and A/C, the correct radiator engineering number to look for is the C8ZE-L, L1, or L2 series, which were the factory big-block radiators.
