P6 2000 booster orientation.

[PNP]

I’m replacing an aftermarket brake booster (a pbr 44 for the other Aussies) with an original Lockheed unit. Looks like the orientation that you mount it doesn’t seem to matter? Having it sit with the vacuum valve on the side would make it easier to install the vacuum hose

The orientation doesn’t matter for functioning, on LHD at least cars Rover always had the air valve more or less pointing up.

Bit of trivia, I see you have three studs on the back of the booster. That is correct for the earlier boosters but Rover eventually went to just two studs. When they did that, the brackets changed before they ran out of boosters and for awhile the third stud was covered with a plastic cap.

You can see on my car that the unit is arranged so that the connection is, as you suggest, in the best position for connecting the hose to the manifold. As Vern notes, you can see the plastic sleeve on the third unused mounting stud on the booster.

I got the booster off a very rusty 67 TC. It still had the plastic cap on it but it fell apart when I pulled it apart

That looks better. I can pull it apart and paint the brackets now.
