Ed,

I was sent a PM.

In 1973, only '43'..... Formula SD-455 Firebirds were built.

* '10' - 4-Speeds
* '33' - Automatics

Only '1' Buccaneer Red {Code 75} was built, and my sister owned it...

If the Automatic was built with Air-Conditioning, the standard Rear-End
Gear Ratio from the factory was a 3.08.

But, you could order the Code #G92 {3.42} Performance Axle, or 'special order'
Dealer Installed Code #CG {3.73 Gears} which my sister's car came though with.

I was told that the 1973 SD-455 also came though with a 'special'
'PQ-Code' Turbo 400 Transmission.

Anybody know anything about the PQ-Code......
