Odd rim I pulled off.......
The one I'm looking for....
K-1-0 4 29 AU dates to 29 April, 1970.
So that would mean that the 1970 Camaro Z28 had round valve stem holes? I thought the early wheels had oval holes?
Or, April 1980 which is more likely as it is a round hole wheel.
That makes a whole lot more sense.
Yup...I missed seeing the hole.
Found this elsewhere. Not sure what he is trying to say about the 70 1/2:
1). Oval hole 1" by 5/8" for 1970 thru 1970 1/2 Camaro Z28
2). Oval hole 1" by 13/16 for Camaro Z28 1970 1/2 thru 1976 & all Chevelle 1971 & 1972
3). Round hole 7/8" diameter for 77 & 78 Camaro Z28 painted car color
4). Round hole 1" diameter for 79 thru 81 Camaro Z28 painted car color
All four versions have the same GM part number & there is also a difference in the surface of each of the "spokes" themselves. The outer flat surface of the individual spokes of a Z28 wheels spokes are flat while the Chevelle wheel spokes are more outwardly rounded.
The 71 & 72 Chevelle "inner ring" of the wheels are flush with the trim ring while the later Z28 wheels are indented about 1/4" and are very noticable.
I think the intent of the 70 1/2 is that the first design lasted about halfway through the 70 production year and then switched to the second design. The first design was short lived and you realize why when you try to get your fingers in there to remove a valve stem cap off a short stem.
I just need to find one more like the oval hole rims I have on there already.
Well, this is some good info. I have discovered that I have one odd wheel, as well. Guess I will have to start hunting for the one I need.
I might have one. Let me get out in the garage tomorrow. Recovering from back surgery. Still pretty sore
