Does it have documentation?
GSD being a Dodge dealer, I am skeptical. I would bank on a 72 Demon supercharger kit being added to it. I have never heard of the GSS package being added to any used car except the Purple 71 GSS Demon. Sequential serial number to mine.
Definitely needs paperwork

There's a difference between Norm equipped, and Norm built. I'd value it as 73 Duster 340 4 spd, then add on the price of supercharger.
That’s for sure. This is the first I’ve heard of a Norms duster. Kim

This car was sent to Mr norm to have the Paxton installed it’s a Mr norms built car not a Mr norms installed car

If you have the Mr Norm's paperwork documenting that he installed the supercharger, I'd ask whatever the Purple 71 GSS Demon would get and be ready to back off that number if pressed - it will be a very niche market. A wild stab for me would be $60-$65, maybe as much as $70K, if the provenance can be proven.

Why wouldn't you get an appraiser to give you a realistic value? Obviously as stated, you need some serious documentation if in fact it's that rare.

I agree. I was kidding.

Wouldn't it be the other way around since Mr. Norm's didn't build the car, but installed the supercharger?
I'd love to see a picture of the hole in the radiator support near the air filter. There is definite tell tale signature of the superchargered cars.
Norm installed HP parts on 1000's of cars. He was the performance Mecca for Dodge. The largest Dodge dealer in the country during this time, IIRC.. Unless it is documented as a GSS conversion, then sorry, it is another car that used his service department for performance upgrades.

The purple GSS is fully documented as a GSS package conversion. This is being accepted as a real GSS in the registry due to this.
