Some of the changes were minor to the HT but they made for a smoother on the eye car such as around the rear window which was widened. Some of the options that were available on the HT models were front disc brakes, Superlift shock absorbers, power steering, power windows, bucket seats, air conditioning and vinyl roof.

The HT had the same body as the earlier HK but was a more refined car. The Monaro's tacho which was stuck in the centre consol in the HK was now where you could see it without crashing. The Australian public by this time had almost become obsessed with V8,s and with Ford upgrading there 289ci to the 302ci GM-H released the newly developed 5.0 litre and 4.2 litre V8 engines midway in the HT's life. They quickly gained a  reputation as being tough and reliable with acceptable fuel economy, especially the 4.2 litre with it's two barrel carburettor.
