Default Wheel date codes question

I have 4 original 1969 Rallye Wheels. They have the AZ code stamped on them as well as the K-1-9 at the valve hole and under the hub cap. Two of the wheels were manufactured in September, 1969 and two were manufactured in December, 1969.

Two questions:

1) Would these wheels have ever been put on a 1969 Corvette with such late 1969 dates of manufacture; and

2) Would these wheels have been used on 1970 Corvettes as I am not sure if the "AZ" marking was used on the 1970 Corvette wheels.

As always, thanks for any replies.

1969 Corvette production ran through the end of December, so if the VIN is late enough, they could have gone on a '69. The "AZ" wheel was used as the base wheel from '69 through '82.

OK, thanks. So this means that wheels would be proper for a 1970 Corvette as well as a late VIN '69.

67Heaven, thanks for the info. I guess I was under the mistaken assumption that since 67, 68 and 69 wheel codes were different, that they were different for all years. Either way I guess, there is only a limited number Corvettes for which my wheels would be considered correct based on the manufacturing dates.

For a NCRS judged car, these wheels would probably receive full credit for a very late 69 (car's build date after the wheel date code) or a 70 built within six months of the wheel date code...say before late June. The day and month of the wheel date code are on either side of the valve stem hole; the stamp should be of the format "K-1-9 12 (hole) XX AZ" where XX is the day of the month.

For the discriminating restorer, these wheels would only be correct for a very late 69 (car's build date after the wheel date code) or an early 70 built in January or February.

Chuck, I knew about the date codes and the locations but figured it was detail not required to post. I didn't know about the 6 month window but I figured there was some window for which these wheels would deemed correct. Thanks again for all the replies.

Actually, the six month window would only count on the spare wheel, since that is the only date code that is visible on the judging field. For strictly judging purposes, the date codes on the mounted wheels would be immaterial since the date codes are obscured by the trim rings.
