Thor coolant pipe part numbers ?

As I've had a few overheating issues with my p38 thor 4.0 I noticed a few pipes giving way.
I've got a new top hose, pump to thermostat, thermostat to rad.
The main steelers are not showing thor engine codes on their systems for my car.
I need part numbers for the following:
I need the pipe that goes to the thermostat the heater return and the expansion tank.
The pipe that from the expansion tank to the one mentioned above.
The 2 that connect the heater matrix out of the bulkhead to the inlet and outlet of the head/ thermostat.
I should have done these when doing the heads, but you live and learn.
Would have given way in these temps.
Can anyone tell me where I can find part numbers for these or have these to hand. Rember thor not jems engine

Now ordered as they found the relavant page. Hope this stems the leaks. Top pipe started to look like a balloon and had little splits in it with the webing sticking out.
