Steering gearbox interchangeability

[Skytrooper]

I was wondering if power steering gearbox P/N G-3643012 is interchangeable with a G-2267262 on a 71 charger.

I have looked for charts online and here, but didn't find anything.

Thanks !

My thinking is that all 66-72 power steering boxes interchange. I'm just not sure of the pitman arm interchange.
