Hello again. I am looking to get the correct alternator, 1100693, 37 amp. alternator for my 67 Camaro but was wondering about how much in advance was the alternator built before the final assembly date? I have found many answers to this and am thinking it might be just a few weeks before? How about up to a month before assembly? My car was built the 3rd week of March, 1967. With that date, I'm thinking it should read about 7C. Possibly 7B? or would that be too early? This is a BB car from LOS, so there is no ac., a 37 amp.
