Hope this helps.

Hello Jacques,
Thank you very much for the clear answer and photos, it is a great starting point… As for the rest of the thread, I was hoping it would stay close to the specifics of my question, since after reading all the additional wealth of information, while useful in many ways (it can become difficult to retain very fast) since we start to deal with other details that are not pertinent at the moment...
Please forgive the seemingly ungrateful reply, but it is not my intent... I appreciate all the additional very technical details, but I was only hoping we would remain within the confines of wheels that use the GM 10 X 7.25 bolt circle with a 4.75" pilot hole and designed with either 8 or 12 studs holding the two halves together. I realize that turns into 2 different wheels and more apparently!
For the sake of simplicity, shall we first classify the wheels that only share the 10 x 7.25 bolt circle with a 4.75 pilot hole? Perhaps that should have been the title of my thread. My apology for it is a huge learning curve here...
To the point, and as indicated by Tony Smith, on the 10 x 7.25 bolt circle wheels manufactured by GM/Holden Australia we have:
1- 16" x 6" (8 bolt split wheel)
2- 18" x 8" (12 bolt split wheel)
The next style would be a 5 x 7.25 bolt circle and 4.75 pilot hole also, unique only to Australian Maple Leaf Trucks, also made by Holden…
A) 18" x 8" (12 bolt split wheel)
Furthermore, I understand that there was also a 20”x 8” (12 bolt split wheel) that shared the same bolt circle with and pilot hole; manufactured also by General Motors in Holden Australia… Is that correct?
Lastly, would it be accurate to say that all these 16”, 18” and 20” split wheels share a backspace equivalent to the 16” x 6.0” (8 bolt) Ford Kelsey wheel which was 4 -1/4”? or...
Does anyone have the definitive answer?? Which would bring us to the next maze of information- that would pertain to all the different axle combinations (with or without wheel spacers) used under these 1.5 ton 133” wheel base vehicles with a combination of either one of these wheels…
