The HG of July 1970 is the last facelift of the HK body: a new grille, egg-crate on most models, one-piece tail lights in the HT shape, new trim and colours. The three-speed Trimatic automatic was launched properly — standard on the Premier and Brougham — and all V8s got improved disc brakes. 155,787 were built, 6,147 of them Monaros; the Monaro GTS and V8s have 10.5in power front discs as standard, while six-cylinder cars kept drums.
The HG utilities and panel vans were built alongside the HQ until late 1971, with the HQ’s 173 and 202 six-cylinder engines, HG gearboxes and an “A” prefix on the chassis number — worth knowing when you order engine parts for an HG commercial.
