Great cars the 164 , check for cracks in front cross member they are known to vend due to 6cyl cast block weight.
Change your diff oil and put an engine oil cooler on it due to Australian temps.
Flush gearbox oil and replace auto fluid .
Any Holden Hg, hk etc alloy rims will fit

Cooling is a problem in the 164 in OZ.

Replace the thermostat if you haven't already done so.

Flush the cooling system and re-core the radiator.

Add a transmission cooler and maybe bypass the radiator cooling of the transmission.

Add an electric fan in front of the radiator.

Check out some of the things I have done on Viktoria, my 1974 164E.

carnut222 thank you so much for the offer. I will definitely keep it in mind. I am so grateful for all the help I have received so far on the forum.

As it is a fresh project I am still assessing the car so I’m not 100% sure what I will be needing.

I have found a cracked RH headlight and the cables that drive the RH headlight wipers are broken.

I have found the RH side has taken a knock at some point and the bracket that holds the headlight wiper is bent. My bumper bar also sits slightly to the left and upon inspection I have found the RH bumper bracket is also bent ( the one the bolts to the bar).

Slowly slowly I will more than likely find little bit and pieces that need doing.
