The Custom SS Treatment

Since we already had the SS grill on the car, I decided to include a few SS exterior trim features on our Nova Custom as an homage to the 1973 Nova SS.

The SS grill is blacked out with an upper and lower bar. Available as an option on all Novas, Dual Body-color Sport "Bullet" Mirrors were part of the SS trim package.

The Black Painted Rear End Panel (that matches the grill) was an SS-only treatment.

The  taillights with bright trim was standard on the SS and the Custom.

We removed the rocker moldings and painted the bright trim

around the door frames the body color.

What makes a "real" 73 Nova SS
In 1973 the Nova SS RPO Z26 was basically just an Exterior Trim package with a Heavy Duty suspension. It could be had with any motor combination including the 6 cylinder 250ci motor. This means that any 73 Nova could theoretically be equipped as an SS. If you are trying the verify a 1973 Nova factory SS you need the original build sheet that the factory would have left under the rear seat.

The list below shows what options both the 1973 Nova Custom and SS included. I have notes after each item that relates to the specific option's inclusion or exclusion on our Nova Custom.

The 1973 Nova SS package included:
Exterior Trim

• Black grille with argent accent on 2nd and 5th horizontal bars (added)
• "SS" ornamentation (badges) on grille, fender and deck lid (grill ornamentation added)
• Specific body side striping (not added)
• Black painted rear end panel with bright trim on tail lamps (added, bright trim existing from Custom)
• Dual body-color sport mirrors (added)
• Bright roof drip moldings (existing from Custom trim)

Interior Trim

• "SS" emblem on steering wheel shroud (not added)
• Carpet floor covering (existing from Custom)

Chassis

• Rally wheels 14x6 or 14x7 with specific center hub and no trim ring (not added)
• F40 Heavy duty suspension (F41 Sport suspension optional) (not added)

The Black End Panel, the Sport mirrors, no rocker and wheel moldings, body color side window trim are all a tip of the hat to the 1973 SS trim package. Badges? We don't need no stinkin badges!
