Question about 15x7 AG rims
We have two 15x7 rally wheels here.
One has AG stamped right of the valve hole
And by the lug holes
K1
8
and GM by one of the other holes
The other rim has 5 AG stamped on the left of the valve hole and upside down
and then K 1 4 by the lug holes and another stamp H 2
Anyone make anything of those marks?

Kelsey-Hayes was the manufacturing for the Corvette Rally wheels. They were very inconsistent in the position of the code stamping on the wheels. It got more uniform as time went on but for early 1968 AG wheels it can be all over the place. Service replacement wheels can throw in more variations.
AG is the wheel type. 15X7 Rally. This was the only real consistent stamp on the face of the wheel. It is always by the stem hole.
K18:
K = Kelsey-Hayes - I've also seen this listed as the bead type of the rim, but I've alway thought it was the manufacturer code.
1 = The plant code - Romulus, MI
8 = Year
The Manufacturer/Plant/Year was typically stamped near the stem hole but can also be found on the spiders near the bolt holes. Some time it was stamped as one line and some times as two. You may also find dashes in between the codes.
There should also be a manufacturing date code somewhere on the wheel. It will be month/day. Most of the time it is near the stem hole. The month is on one side of the hole and the day on the other. If something is not stamped by the stem hole or a spider it could also be stamped on the barrel of the wheel where it is not visible with the tire on.
I've attached a couple pictures to show some of the variation in 1968. On my 1968's Jan. 31 manufactured wheels (last picture) they didn't even stamp a year code. I've seen wheel produced the very next day where they did.
