You could order the Code #G92 'Performance Axle' {3.42 Gears} as an
option on the A/C equipped Formula SD-455.

Just how my sister's car got the Code #CG {3.73 Gears} was baffling,
because it was not on the Pontiac 'available option list'.

Not that it was a big deal at the time, as we never dug into the
"Who and How' it got that set of 3.73 Gears.

Later we were told that Lockwood Motors Pontiac, who were also
Pontiac Racers, had the car 'special ordered'.

Maybe the 3.73 Gears were placed 'in the trunk' and installed at
the Dealership.

Though I'm a Mopar Guy, that Formula SD-455 was a sharp looking car,
and easy to drive.

Tuned up, and with the A/C and P/S belts removed, I'm positive
that car with 3.73 Gears could run 'Nuts On' 13.00's.

Code #LS-2 {SD-455 Engine}
