    so if it was a beautifully restored alternator with Seth's dates you would accept it as an original alternator on a low mileage car.? I think not. That was my point.....
    We don't judge whether anything (aside from trim tag and legal VIN) is original to the car.

      Good time to clarify whether we are talking flight judging or bow tie judging. Different standards, obviously.

        Maybe it wasn't obvious from my post but because it is presented as a low mileage original car I am assuming we are in the Bow tie category. The discussion here is wether an out of date alternator may be original. If that was the case during flight judging with a restored alternator it would definitely fail on the date. My thought was if it was an unrestored alternator on a low mileage original car then there is an argument to let it go through.

          If we're talking Bowtie, then the 6 month rule (or pretty much any Flight Judging procedure) does not apply.

            Just my opinion.......
            Dave,

            Do you mean several dates after his?
            I don't have them handy, but I think there are batches in August (like his), December (I believe mine is this date but the car isn't handy) and February (like yours). There may be an April date too.
            Do you know of others?

              Patrick,
              i don't recall them as being in batches but that is certainly possible and I didn't document them either but I do recall seeing them all within the 6 month range. My memory is from 1971 cars. You can see mine is 4 1/2 months out.
              Your car is a 72 so maybe the batch thing was more toward that model year.
              As you know early 544 alternators (1971) are very scarce. As I mentioned in my earlier post I think Seth's may be original as long as it fits the patina of the car.

                My blue car is an early June 71 car; you know my yellow 72 car.
                I have done a lot of searching and watching for 1971 MY 544 alternators, and those are relatively rare birds. Most of the ones I see seem to start July 1971 and later. That doesn't help a 1971 MY car at all.

                  I try my post on this place.

                  I'm also searching a 71 July 1100544 Alternator for my early 72 (...540) car. Im not sure about the rectangular shape under the Delco Remy Logo. Did the early 72 Corvettes with this alternator 1100544 still have this rectangle or were they already without it?

                    For what it is worth- the '71 LT1 (purchased from the original owner) I am currently restoring has a number of components (starter, smog pump, alternator) that are just out of the 6 month window from the car's mid March build date. Can't say for sure the components were never changed but if they were replacements it seems strange the replacements would all be built in the '70 July/Aug timeframe.

                      Someone know it? When exactly did it change.

                      Thanks!

                        Re: 71 Alternator Date Code

                        Can anyone help me with the answer?


                        The NCRS book says in 1972 this small rectangular no longer existed. Does this also apply to the Corvettes produced in '71 with the model year 1972?
