There are differences in the trunk floor from year to year on the spare tire hold down area. Early cars had the hump while later had none. Early 68 Novas had the ear and actually had card board inserts to keep things from falling into the void between the trunk drop, and qtr pnl. 70s don't have the ear that I've seen although very early ones might. If this car had trunk drops replaced, the repops do not have the "ear". That would be my guess. Again, from what I see, it looks like an older restoration. FWIW
