What I am sure of is lots of Jr. Stockers would have loved to use a P/O rear, but instead, they went through untold grief with Chevy "P" cases and all that junk.
The Pontiac/ Olds setup was common in the M/P and Gas classes.
If the rulebook still says "of the same manufacturer" , NHRA always took that to mean Chevy, one , Pontiac ,two , and different.
Now, if it says something about "corporate" , then you boys may have an argument.
But then again, it seems they have already spoken on this, many years ago.
