The HD was not received very well after the much loved EH for a number of reasons, mainly the new shape with the front guards receiving most of the attention. The HD body was all new but underneath was still the same narrow track as in the EH. As well as this, the engine was sitting 67 mm further forward!
The older brakes were not up to the heavier body of the HD and mid-way in 1965 Holden released a new ball-joint front-end with twin-pot disc brakes as an option! Even with these features the people were turning off the US designed HD and GM-H decided to end it's life sooner than it had planned. This model takes the record for being the shortest lived Holden ever on the production line!
This model however made an impression with it's X2 which sported twin carburetors and 140 bhp among other upgraded items.  This was the birth of the Holden sports sedan and the public were at least happy about this.
