The pinion and ring gear are different in every gear ratio set. That is what makes them 2.73s or 3.08s.
No a pinion out of a 2.73 won't work in a 3.08 rear. (if I understood the question correctly
)

if it has the same number of teeth it should. provided they are both the same size rear. cannot put a 8.5 gear set in a 7.5 rear.

1) It won't fit because the tooth count is different
2) It won't fit because the Malibu is an 8.2 rear and the firebird is a 7.5 rear.
Just get a new ring & pinion. They are cheap for 7.5 10 bolts.
