could be right then, but it could also be the linkage from the selector lever forward to the gearbox selector arm. That is simply a stainless M6 threaded rod with 10mm ball joint nylon sockets fitted at the ends, totalling about 18cm in length. The joints often seize, break or distort, which could prevent accurate selection of "P".
The Rover part is NLA (if it ever was available), but can be easily repaired by replacing the ball-joints:

Generally, but not always, failing to start
some of the time in "P" is a inhibitor switch problem;
never starting in "P" is a selector rod mal-adjusted or damaged.
Inability to select
any gear position, "N" or "P", is a broken ball joint, generally the one at the gearbox end of the threaded rod.
The inhibitor is a Ford part, and is actually called a "Neutral Safety Switch".

This video is for a Ford F-150 truck, but it has a very similar gearbox to the Rover 75V8 (4R70W instead of 4R75W), and uses the same Neutral Safety Switch.

Lots more information over on the The Two Sixties, specifically for and by ZT260 and Rover 75V8 owners. You really should join; it will save you a bomb in the end. Did for me.
