1971 Demon Sizzler

Hello all, I'm new to the site.
I picked up a '71 Demon Sizzler earlier this year.
The car is B5 blue w/white stripes, 318/auto, full project but very straight. Motor and trans are gone. Does anyone have somewhat accurate production numbers for these? I've seen a full range of production numbers on the web for the Sizzler. Not sure yet if I'm going to keep it or sell it.
I appreciate any help.
