Two Steps Forward.... One Step Back?

After some more stupidity by TNT my replacement gearbox eventually turned up at work today, now I have two:I refitted the bellhousing and clutch fork and fitted the gearbox to the engine. Slight problem though.... the clutch release fork has ended up too far back in the bellhousing for the slave pushrod to fit. This also leaves no allowance for clutch wear:I checked that the clutch release bearing was fitted to the fork properly..... it was. This leaves the ball spigot as the likely culprit. Mine needs to be shorter to produce the correct fork alignment. Looks like a call to BAE tomorrow.

Of course there is always the chance that I've done something daft..... but I don't think so.
