Duster race weights?

Who has weighed their Duster?

I know the later ones are heavier due to doors and bumpers but I assume they can be setup similar to a '70-72. I am talking a complete race car though with no street equipment. I also know it will depend on engine/trans/rear end...etc but I'd like to know in the ballpark.

I raced one years ago but never got to weigh it. It had poly race buckets and a gutted interior, no heater box, radio or anything associated. It was a '71.

Wondering how light I can get one.
