Like any car...only way to figure them out is to see them in person. Looks nice, but as stated there are lots of questions to consider.
Note the std. door panels...that probably indicates this was a rubber mat car at birth, and the buckets were added...maybe..??
Intake looks like a flat #569 which is correct for 70 L78...
All of these Novas seem to have the same issue...the SS badge is always upside down on the front grille
You probably couldn't build an L78 clone for the asking price...worth a look if someone is close by.
