It was my understanding that all the "NEW" cars (Ford, Mopar and Chev) get to run the 9" Ford with either the cast iron or ALUMINUM case................

The old rule about replacing a Factory rear end with another Factory rear end that was listed in the Factory parts list is not allowable at present.

Strange had a Aluminum case for the 9" listed in the Ford parts list and it was accepted by NHRA for about 20 years, now the only cars that can run the aforementioned case are only cars that were available from the Factory with the Aluminium case.

So let me see if I can get this straight....As of now I can't run an Aluminum case in my Pre 2008 Stocker (9") because it was not available from the Factory, but a Post 2008 Non-FORD car can???

Yeah, makes perfect sense too me.

I am not changing my r/e case for Indy.

Luv ya Jeff!!
