A local friend of mine has these wheels that he took off of an all original 71 GTO when he put rallys on it. He has since sold the car and has the wheels for sale.

The wheels have date stamps that are different than any I have seen before. They also have a 5 digit number (21080) stamped on them and a couple of codes stamped near the lug area that I have never seen. Any help identifying them would be appreciated.

I have some I will check them out today and see if they have those part numbers on them?

Lyn.

Thanks Lyn

[carguy66cars]

Well won't be any help as the one's I have are AH code 15"x7"?

Lyn.

[1oldgoat]

Thanks for looking.

This is what I have for the HF - 1971 STANDARD 14 x 6 3987808

Not sure what the 21080 is unless it was a service replacement wheel with its own number?
(the 3987808 is the part number shown for the HF)

The date not sure, possibly Aug 70?

What does it say to the left of the fill plug- 11P or UP?

710 or 71D for the first set of numbers?
(or OIL upside down )

To the left of the valve stem is HF. If you zoom in you can make it our fairly clearly. Bad picture taking on my part.

The other set of stampings look to me like "T10 8"

[The Boss]

Mine are dated 12 8 in the conventional manner.

Sorry, meant to the right of the plug.



I'd say the date is probably Aug (11?) of 1970.
The T1 is probably the manufacturer.

Ok found mine, but not sure helps much, hard to read the date?

Scott, Believe I have a similar style dated & coded (with the T) 14" wheel. Will be out in the wheel stacks this weekend & see what it is

GM used several different steel wheel manufacturers in the '60's & 70's, including Kelsey-Hayes which made many of Chevy's steel wheels, unfortunately, thus is not a K-H supplied wheel.

The typical Pontiac usage date coded steel wheels that most of us have was made by MotorWheel. MotorWheel also manufactured most of the OEM Rally II's. One will typically see the M above the year date code on MotorWheel mfg wheels. Have a feeling the wheels that date code begin with a T, like on your above pics, were made by Norris Technologys. Tough to find date decoding info on these.

Thanks Roger. I just talked to the guy who has the wheels and he told me the car they came from was a Fremont built car he thinks it was a 12C production car.

Roger, have you ever seen the 5 digit number like that before?

Not that I can remember, but on the wheels I'm thinking of, I was fixated on the T & string of numbers, wondering how to decode. Have had nearly two dozen '71 Fremont built Pontiac A-bodys as partscars & projects, will see what have in the stacks & on current partscars.

[Ram4king]

I have over 20 of these wheels and not 1 of mine have those numbers yours have. Don't know what to tell you.

Hey Don. Do you have any idea how to read the date code?
