Re: How do you ID original GM rally rims?
There is also a date code on the wheels which will help id them.
Code is on the rim by the valve stem hole as well as some of the information on the face or the wheel.
K1y m (Valve Stem Hole) dd aa
K = Kelsey-Hayes
1 = Romulus, MI wheel plant
y = calendar year
m = month
dd = day
aa = application code
When looking at original GM wheels, they will be stamped around the edges of the valve stem. This is good information to have, because it gives you the size / backspace / production date of the wheel. Below is a list of the available GM information;

Here are a few extra notes:
* All the rally wheels made in 1967 have big marking letters, no date code, a little bit different shaped center and slightly bigger holes in the center.
* The 15x7 beauty ring will go on all the 15x6 wheels.
* All the hubcaps interchange with each other.
