But the 8 spoke weren't the only wheel being used...

But most teams switched to 8 spoke wheels around 1969.
Additional information I found on the internet (so it must be true
)
Old Race Car Wheels.
I found several references to the 8 spoke Minilite wheels being used in the Trans AM racing series as well as how not stock many of the real race cars were.
I guess we are both right!!
