Does anyone know the thread size of the high pressure power steering hose fitting on the end that connects to the steering box?

I was replacing my leaking hose last night and it appears that the old hose was cross threaded into the box (the threads on the old hose are messed up). I can get the new hose to start to tighten up and then it breaks loose. I quit trying after a while so that I don't f up the threads on the new hose. The old hose will tighten up but I cut it to get a box end on the other fitting so I can't put it back on and I decided to do this when my wife is out of town so I don't have a vehicle. I am planning on trying to tap the steering box unless someone has a better suggestion.

Thanks

Did you ever find this? I was looking at these myself the other day. I want to say they are 14mm and 16mm o-ring fittings. At least that's close to what they measure out to. Unless they are SAE sizes, but I thought I read they are metric somewhere.

Never figured out the thread sizes. I did use a 14mm and 16mm socket to get the lines off the box after breaking the pipes off near the fittings. I think the pump side takes a 5/8ths. I thought I had cross threaded the fittings at the box because they were sitting a little proud but some thread sealer and serous torque with a flare nut wrench seems to have worked.
