Would the date codes on a 69 and 79 rally wheel??

[george culolias]

The same? Is there some other way to tell the 2 rims apart? Thanks for everyone that has been helping me I'm learning.

Re: Would the date codes on a 69 and 79 rally whee

I may get corrected here but I'm learning, too. The first thing I learned when I joined the NCRS is that it's best to get a judging manual.
Both wheels should have AZ stamped on them for Corvette application. Look where the valve stem hole is. Example for a 1969 on the left side you should see K-1-9-X. K=Kelsey, 1=manufacturing plant, 9=1969, X=month as in 1-12. So, K-1-9-10 (10 being October) could be considered okay for an early 1970 Corvette to April 1970. On the right side should be another number which is the day of the wheel build and than AZ. Example: K-1-9-10-16-AZ is October 16, 1969. For a 1970 wheel K-1-0-3-25-AZ would then be March 25, 1970. This would not be okay for a 1969 Corvette.

Thanks for the reply, I read about date codes in the manuel, but what I don't understand is, since 69 and 79 have the same year ending date would they have a different date code? Are the wheels identical?

My apologies. It was late and I misread your question. 1979 didn't have rally wheels such as the ones in 1969. Beginning in 1976 they came out with the optional aluminum alloy wheels and by 1978-1982 they came standard with aluminum alloy wheels.

To close the loop here...by 79...the same date code format was in use but in 78 we begin to see the day and the month turned sideways to be read. By 1980...two digits were used for the year.

Nice pic Tom. What's the YA?
FWIW: There was a three or four part story on the subject of rally wheels in The Restorer back about 4 or 5 years ago (I don't have my CD with me at the moment, and don't have the time to look it up in the on-line Restorer story index). Those articles were exhaustive, and I suspect contain the answers to these questions.

Scott:

I think you will find that aluminum wheels were never standard before 1984.

A friend's 82 came from the factory with the rallye wheels. It looked really odd since most cars were equipped with the aluminum.

Tom--
You're right on with the rally wheels being available through 82, from my experience.

See? I told you I'm still learning. I've never seen a Corvette past '77 have rally wheels and for sure would look odd on the fat back '78-'82s. Can you imagine an '82 Collector with rallys?

Another way to tell these two rims apart (1969 vs 1979) might be color, if compared side by side. I think a greenish hue silver was used on 69-70 while silver absent of green hue was used on all other years. For sure this was the case for 1970.

Re: YA is the 78-82 Polyspare tire rim...

Broadcast code called on the build sheet and stamped on the rim for the donut tire installed on the 15 x 5 rim.

You couldn't get a collector 82 with ralleys. The wheels were part of the collector edition package. It would be extremely ugly othherwise, wouldn't it?

Scott -

"AG" was the one-year-only '68 Corvette 15x7 standard rally wheel.
