Update.
Measured axial play and it isn't as bad as I'd thought. It is 0.9mm.
Which is still over the permitted maximum of 0.75mm but only by 0.15mm. There is no discernable play on the other side (which to my mind implies worn clutch pack on one side rather than wear on the pinion cross shaft and/or C-clips).
The locking is working - I tested it with a wheel off the ground, forwards and reverse.
Given that the clutch plates are still suspect, and unless anyone thinks this is a very bad idea, I'm going to run with it for a bit and keep monitoring the play. If it is clutch wear it will surely gradually worsen in daily driving (as even without invoking the mechanical locking, during any kind of cornering where there is cornering force and a speed differential over the axle, the inner wheel is applying pressure to its clutch pack such that there is an element of anti-slip).
I will very likely be changing the clutches at some point so any info on that that anyone has to offer - please post here. Also, anyone running a G80 might consider - when they have the rear wheels off the deck - releasing the parking brake and checking for play...
Anyway, that's my plan - unless, like I said, anyone thinks it a bad one.
