			''If the gearlever travels too far towards the dash (knuckle rash into say reverse) it could be some of the adjustments or wear of parts below, but also a bent gearlever in 2WD T25s, however unlikely,check the lever first.''

	You might be able to correct this by adjusting the spline joint position (radially) under the centre of the vehicle, but more likely its wear....		You might be able to correct this by adjusting the spline joint position (radially) under the centre of the vehicle, but more likely its wear....

			Remove the protective tube to watch the spider uj - these can develop wear, but usually after other bushes are causing more 'lost movement'. If you do the spider, make sure the pins (retained with circlips) are located fully in their detent slots when re-assembling - if they aren't they'll rotate and wear the steel forks rather than the plastic spider - requiring a new shaft!----

			Good luck, not a 5 minute job, nor that cheap if the front needs doing.
