Can anyone help with the thread sizes please on the power steering rack.

We're rebuilding our Impreza, has an Sti quick rack in it, facelift car. Where the pipes feed from the power steering pump in to, and back from, the steering rack are two threads. Does anyone know what thread size they are? One appears to be bigger than the other? We are running goodridge houses so I need to order the correct sized connectors, it's hard to tell from the ones that have come off the car. Thanks
