One again there are 2 types.

Number plate earth screw.

Please note all these screws and bolts are genuine Holden parts.
Not someones interpretation of what the are.
Lots of ebay sellers annoy me with there shit reproductions.

Fuel Tank Bolts.

Here are the fuel tank mounting bolts.Once again there are 2 different types one long and one short.
The bolt is silver Zinc and the nuts are gold.
These bolts are on there own 2 per car and that's it.

Tail lamp clip.

These are the clip that mount the tail light housing to the bumper bar.
There are 6 per car.
Surface finish Black Zinc.
They are only used on the rear bar NO Crossover.

More NOS parts

Here we have upper control arm bolts. These are black in colour. Take note of rust on surface this is typical of NOS parts way overrated in my opinion.
Work has to be done to bring back that pristine original look.
These ran for the entire range from HQ through to WB. Thats a lot of bolts

Spacers and panel gaps.

If your car has front panel gap problem this is usually why. These control the cowl to bonnet gap and also your guard to front door gap. These are used in all sorts of configuration's sometimes two on one side and one on the other. These cars are quite difficult to gap so be patient with the old girls. Remember always start to gap you car from the rear quarters it is the only way it can be done correctly.

Front panel bolts

This is a front panel bolt from a 12/1972 HQ SS Sydney car. The eight that secure the top of the front apron and lock panel are in silver zinc so to are the 2 securing the fenders to the cowling. (The six inside mounting to the pillar are silver Different bolt and washer) the rest are in grey black metal finish, I have noticed all Sydney cars I have are the same.

Brake line bracket to frame.

Steering box bolts

Silver zinc black washers.

Lower control arm bolts

The lower control bolts are silver zinc and the nuts are gold zinc. Some cars have silver nuts. This 12/72 SS had gold zinc so that's how it will go back together

Front bar bolts

The front bar bolts(bracket to frame) consist of two colours silver zinc and gold zinc(AS PER FACTORY)
There is a letter present on bolt head (S)

Frame bolts

Frame bolts there are eight of these these ones are coated in gold zinc. The reinforcement plates are finished in bare metal. We have coated ours in paint grip which is a clear flat coating and will prolong rusting. The washers are glued(contact cement as per factory) to the rubbers to inshore correct alignment on assembly.
Two more of these secure the radiator support and are no different to frame bolts. They do have a nut which can be seen in photo they are square. I have seen these in gold zinc and silver zinc this Sydney built car had gold zinc.
