T-3 head light date code

[Smokey]

I haven't payed attention to the date codes, but the crystals have a pattern from early to late cars. I noticed this in the Impala's with their 4 headlight system and parting quiet a few of them out.


Like when we had our 63 SS car, a friend had had 4 63's in his backyard with the original T3s and they had different patterns to them and they were still the born with ones. Its interesting if someone could figure that code out. I had one that was burnt out..and another with a chip in a 29k mile virgin.
