Power Assisted Steering boxes. 3-bolt vs 4-bolt

Hi.

My Range Rover -84 model (SALLHAMV2AA) needs a new PAS box. The one installed in my car is a 3-bolt type. I ordered a reconditioned one from Paddock, but they didn't have any in their stock. Instead they suggested that i could use a new 4-bolt type. Does anyone know if i can replace the 3-bolt with a 4-bolt PAS box??

Please help me out here. I don't want to order a box that doesn't fit.

I did find the answer.

The 3-bolt is no longer in production. The 4-bolt will fit the car, but the hose fittings are metric instead of imperial on the 3-bolt.
