My 1968 Valiant 100 Overhaul begins. :)

Signets generally have chrome (? may be stainless steel; haven't looked that hard) side-window frames, a trim strip between the tail lights on the lower edge of the decklid and rocker panel trim. 100s...Generally have body-color window frames, no trim strip between the tail lights on the decklid and no rocker trim. The grills are the same. The dashes are different.
