NOS 71 sharktooth grille & bezels

I would say at least $2k also. If a repop will be in the $1200 neighborhood, then NOS will always be worth considerably more.
From a distance of a few feet, a lot of reproductions look nice, but close up, they are identifiable as a repop. Case in point, my '68 Road Runner finish panel. Yeah, they make reproductions of it and the '68 GTX panel.
From a distance they look good, up close they lack some of the detail.
