This page is for the 1973 Firbird Formula 350 of which I recently aqquired from my brother.
We located this car in Lethbridge Alberta in 1997.
The car was purchased as a complete numbers matching car.

The only available gearsets for 1973 Formulas were: 2.73:1 / 3.08:1 / 3.42:1.
If you did not specify the gearset, depending on what drivetrain you ordered, this is what you recieved;
A) any engine w/ a manual transmission = 3.42:1
B) L30 w/ automatic transmission (TH350) = 2.73:1
C) L78 or L75 or LS2 w/ automatic transmission (TH400) = 3.42:1
D) either 'A' or 'C' w/ air conditioning = 3.08:1
The options for this exact car were:
-Automatic transmission
-Power steering
-Power brakes
-Rear window defog (fan type)
-Ralley gauges w/clock
-AM 8-track dual speaker radio
-Front seat center console
-14x7 ralley II wheels (w/ full size spare)
-Custom cloth delux interior (two tone cloth/ corduroy/ vinyl combo)
-Exterior chrome dress up
-Rear bumperettes
*-this is an early build 1973 car, so it has many 1972 style interior pieces (the most obvious being carpet and headliner)
This car was ordered as an Ascot Silver car.
This is how the car looked when we found it in 1997.
