Do those in the know know if you are allowed to put a single cab tray on an extra cab chasis? not worried about weight distribution etc. Just whether you can do it or please suggest a place to find answers.

The overhang behind the rear wheels allowable is actually 60% of the wheelbase, or 3.7M, whichever is the lesser measurement.
So that means you probably can fit a single cab tray to a dual cab.
But the average single cab tray is 2.4M long, while the average maximum length for a dual cab tray is 1.6M.
The extra 800mm is going to stress your chassis an enormous amount, and I personally, wouldn't recommend the fitting of a 2.4M tray to a dual cab.
In addition, a very long tray such as you are thinking of, will seriously affect vehicle handling when loaded, causing vicious oversteer, if you do even a mild swerve.
Google "bent ute" and images, and you'll see plenty of examples of bent chassis' on dual cab utes, that generally have a lot shorter trays than 2.4M.

Won't make a huge difference but the question was for a "space cab, extra cab", not dual cab. And if the make of vehicle was given it might have helped a bit.
For example, Triton vehicle has 3000mm wheelbase current
Ranger, Mazda have 3220mm wheelbase.
Average tray length for Mazda extra cab is about 2000mm.

Ahh, my error - I misread space cab for dual cab, because dual cabs are in the vast majority.
The red space cab
Ranger on the tray manufacturers site below, is fitted with a 2.4M tray, the same length as most single cabs - so it's legal.

However, there's another angle that rears its head here, as
well.
If the OP is changing the overall length of his already-registered vehicle, he will have to have the vehicle re-inspected and re-measured, and the rego record amended accordingly.
Cheers, Ron.

G'day Gusthebus, I have a single cab Dmax with the 2600mm tray. There's 1340mm from the centre of the rear axle to the back of the canopy and I have a tool box behind each rear mudflap, spare wheel and towbar.
I'm not prepared to put any more weight behind the rear axle and I don't tow anything.
However some single cab trays are shorter than 2600mm so you may be OK.
I live in
Cairns and you're welcome to have a look at my ute if you're interested.

Thanks for the offer. This one sticks out 1540 from axle. Just surprised to learn how far out they csn legally go - 60% of wheelbase. Great time of year in
cairns eh.
