If you are asking the lug nut bolt pattern it's 5 on 4 3/4
only a Buick, olds or Pontiac engine will bolt to a Pontiac tranny as Chevy blocks have a different bolt pattern.
Some Pontiacs came from the factory with Chevy engines. If this is the case on your 79 firebird, then the transmission will bolt up to a 350 Chevy. If the car came with a Pontiac engine, then the bolt pattern is different and would not bolt up.
Yes, it will.
