Think a L2 radiator would not be correct for your time period. Of course you'll be checking for the date on the radiator to compare it to your 11/1/68 car build date as you likely will for the fan also
You're right.....I hadn't thought about that yet. I have seen an L1 with an Oct 68 date code but so far that's the only one I've found. Haven't seen any L2's but I'd have to think they would be beyond my build date. Thanks for the heads up.
