I am getting ready to try and sell a car for my brother.  It's a 1994
Pontic Firebird Trans-Am with the LT1 Engine and RAM air, and 4 wheel
disc brakes and 65K miles.

My brother said that a mechanic once told him (at a Pontiac Dealer)
that the RAM air must have been installed after the car was built
becasue RAM air was not an option for this car in 1994.

I found some place online that seemed to verify this.  This place also
seemed to imply that 4 wheel disk brakes were not an option or this
car until 1996, but I had to have a pinion gear replace the other day
and the mechanic told me that the back disc brakes still some kinds of
retainer pieces that are only there if it was original from the
factory.  He said this car must have come from the factory with the
rear disc brakes and that they had never been replaced before.  I
asked this mechanic to look at the RAM air system and tell me if he
thought it was an aftermarket setup, or if it looked like it came from
the factory.  He said he thought it looked factory, it even has the
right hood for the RAM air.

Does anyone know if these options were available in 1994 for this
car?   Or is more likely that someone bought this car and then had RAM
air and rear disc brakes added and made to look like factory....?

Thanks
