This is a car I didn't know about. From my records I'd put it on the cusp of 1966/67, between December and February. Can't tell if it has ATE or Dunlop brakes, but I'd guess it came with Dunlops new.
Grille is a second series (1968ish), probably changed during repairs when first series wasn't available, or something.
Great project, wish I had room. Looks very much like my first Super, originally white, painted silver, gone flat like this one in the SoCal sun.
