So I picked up 4 XG rallys for my 69 to convert to discs. I saw the 1966 date and figured they were for a 67 Camaro. But just had a chance to look at the CRG page and 67 used a different code. Now I am confused. All 4 wheels are date 6/19/1966. Were XGs used on another car? thanks
My thought would be Measure the width of the Slot. I might have this worong, When did the Service Wheel slots go narrower from 1-1/8" to 1"
???? could be 1970
Could it even be possible they got the 6 & 9 mixed up and this is merely a 1968 Service XG 14 x 6 Disc Brake wheel.
I can only find XC for 66/67 and that is 5inch wide wheel
additional dating can be found on the barrel.
Thanks! You are correct, 1" slots. So Service wheels, probably 1976 based on the surface pits. I had forgotten original rim stamps are read from outside, service rims are read from inside. Mystery solved. I am good with service rims :)

Maybe in General terms, but this is not a fast and hard rule:
Take my Early "DF" 15 x 6 Z28 rims are factory and are read from the inside. I am sure there are other exceptions to this. Same photos
