The Gemini was being upgraded and released as a new
model in quick succession in the late 1970's. Just 3 years
after its initial release the 3rd model was introduced
as the TD.
The most noticeable visual change was the introduction
of more attractive and up-market looking square headlights.
The grille was, as always, changed again and now the little
Gemini incorporated RTS (Radial Tuned Suspension) which
was much heralded in its big brother, the Holden HZ.
RTS was to take the Gemini's handling to best in its
class, as RTS offered such technology as anti dive geometry,
stabilizer bars front and rear and a panhard rod rear
end.
In all there were seven versions of the TD that included
the TD wagon, the panel van and a luxury SLE model. Today
they remain highly sought after.
