Bought new gaiter
Any tips on removing the old one please ?

If it’s same as the auto you just gently prise it up and off from around the silver trim.

Silver trim should lift and to remove the gear knob you pull the gaiter down away from the gear lever and that releases the clips that hold the knob on to the stick,

Removing the gear lever is a case of just pulling it up and off ! But, if it was only that easy.
The gator should pull down away from the knob.
Then the lower part of the gear knob has two plastic prongs which grip a recess on the stick.
It does pull up, but needs a firm grip and very sharp pull up.
The trim just levers up, use a plastic trim tool, or you could grip the gator and pull.
The leather is held under the plastic trim by small clips.
These are quite fragile so take it easy.

Take some photos and show us how you do it.

Yes its surprising just how much upward force is required. Jules
