Some of the upgrades I've made to our '73 Nova Custom Coupe are pictured below. My goal has been to keep the exterior and interior close to stock and do most of the upgrades under the hood and under the car, while still retaining a "period" look.
Exterior
R-134a Upgrade -- Classic Auto Air
Auxiliary Under Dash Instrumentation
In-Dash Tach -- Shift Right
Holley Carb, Edelbrock Intake
Disc Brake Conversion for 14" Wheels -- Right Stuff
Front Suspension and Steering
Rear Bumper Filler -- Reworked Replica Plastics Part
Rear Bumper Filler Finished
Front Bumper Filler -- Excellent Used Part (Replica Plastics part was unusable)
