Perhaps old street machine magazines and the like might have advertisements for those conversions.

Somebody did a bogie drive one of these for Summernats burnouts many years ago, from memory I think it was some transmission/diff business' work ute, I can't remember their name though.
I'd be interested to see how they set up the diffs and whether they are doing them as a kit or similar. Anyone have pics or even remember their business name?

Brickie friend of mine had a HQ based one in the 80s.
He loved it apart from one problem he had.
On uphill sharp turns, like Bulli Pass, the lazy axle took weight of the driven axle.
He took about 4 goes to get around that corner once.
If you remembered to drive it properly you could reduce the wheelspin.
An LSD would have solved the issues no doubt.
He liked it because it was nicer to drive than the F150 and F250 that were also in his fleet.
He sold it though not long after having the difficulty and bought an F100.

Hi Rodomo, nah it's not one of those. They look to have a bolt on axle and the extension from the rear of the chassis rails. Mine looks to be extended from just behind he cab and everything is properly welded including fish plates. Need to pick it up and get some photos! I also found a crowd (Em-Care) who used to do it as part of creating an ambulance from the one tonner variant.
Hi Rob, I can see how that would be a problem. The guy who rebuilt it with the new driveline says its got an LSD in it so that should help.
It's also a tipper, rad.
Edit. Thanks Byron, having the load ratings would be very helpful in determining what we can go to. It's not that I want to go to 2T but we are looking to go higher than the GVM that is currently listed (2660Kg) obviously. Good to know that all that other stuff is uprated and I'll pass that to the engineer. Unfortunately we haven't been able to find an uprated GVM placard. The point about brake bias has been considered and I'm going to add adjusters between each of the three axles to get that right. It will need to be brake tested so doing this will help passing that, especially since we need to test it loaded to whatever GVM we arrive at!

Here are HZ commercial weights. These are the standard vehicle, so for the cab-chassis that will be 3.3L, 3spd and salisbury rear axle with front disc brakes. This is why only 2600kg is shown for the GVW. V8 is 2660kg. The top line of figures on each row is lbs, bottom line is kg.
The cab-chassis Curb weight (full of fuel) is 1287kg as you can see this leaves you 1313kg for a tray plus load, so only allows for a 313kg of tray leaving you with 1 tonne of carrying capacity which obviously includes people and other stuff like towbar and options such as A/C, power steering, L31, M41 etc. Note that on the second file the V8 cab chassis GVW is 2660kg but its Curb is 1359kg which is 72kg extra for the 4.2L V8 plus whatever extra stuff the V8 gets, which means you have already lost 12kg from your GVW as the V8 cab-chassis is only 60kg higher in GVW than the 6cyl. Add on L31, M41 (100kg over standard), A/C (43kg), bucket seats (6kg), power steering (9kg), towbar (12kg) and with a decent tray you can really soon see your "1-tonner" has suddenly become a "900kg" without accounting for driver.
You can also see that there is no max and min front axle loadings for the V8. So using the 6cyl figures, you can only put 1000kg on the front axle out of 2600kg, and on top of this you cannot have less than 757kg on the front axle when the vehicle is fully loaded at 2600kg. So by upping the GVW to 3600kg with an extra rear axle, sure you can probably now fit 1792kg+1000kg directly over the pair of rear axles but that leaves you with only 808kg on the front axle which is in between the minimum and maximum allowable. However if you move that 2000kg forward a fraction to distribute the load better, it wouldn't take much at all to suddenly see in excess of 1000kg on the front axle. What I'm getting at is properly loaded with 1 tonne and with a light alloy tray the front suspension of a HZ cab-chassis is at or near full capacity. By converting it to a "2 tonner" and distributing the load you'd have to be really carefully that very little of that 2 tonne is loaded biased towards the front axle or it will be overloaded as the front axle has not been upgraded. Then loading in this way you may find the car is not all that stable as the back would be very heavy and the front would be light in comparison. The Engineer you are talking to will be far more versed in this than me though!

Just keep adding axles...

My painter is about to start work on a 6 wheel Statesman ute.
My God it's fugly !

Byron, isnt the lever from the chassis to the brake system the solution to brake bias with a load on it?
I was told that is what it was for.
Cheers

Thought some mentioned Brazier Mobility - Les Brazier Special Vehicles in Adelaide . Not sure but you can find there number in Google Search. Ray
