One tonner cabs

Are all one tonner cabs the same? I have a hz one tonner and I'm going to replace the cab and put all the interior in the new cab. Am I limited just to a hz cab?
Cheers

They are basically all the same as far as bolting up to the chassis. The only one that is not fairly easy to swap if you want to keep your interior is the HQ, due to the dash mounting. WB does need new inner seat mounting installed if you want HQ-HZ bucket seats, that is not difficult but does need to meet design rules for roadworthiness. (May need an engineers tick)

The others do all vary slightly from model to model but HJ-HZ are close to identical. Standard cabs from HJ-Z have the HQ bonnet alignment. Special order "Ambulance" or modified cabs will have HJ-WB bonnet.
Finer details, HJ uses the same electrical bulkhead plug as HQ and the same rattrap clutch attachment, but is otherwise so close to HX-Z as to not matter.
It will take a real expert to pick the difference between a HX and HZ cab if the plates are not attached. Comes down to a couple of holes in the firewall.
Other things to watch out for are the HQ Brake pedal to booster push rod, and the WB pedal booster setups. HJ-X-Z clutch pedal arrangements vary too. HJ will have a rattrap.
HJ heater box in standard tonner wont support the two central vents for forced ventilation.
Until you have it all sorted do not throw out or sell anything that is attached to the firewall in either cab. (even the screws). Try to get a replacement cab with all the firewall accessories still attached.
