Gday guys, i have a TF and i purchased a TJ Sports Gear Stick and have now realised that i am going to have to change my metal stalk bit to be able to fit it, i have been told they are change-able?

I was at Jollys 2 days ago, having a crack on getting one out of a TJ but had no idea how to get it out or even where to start? so does anyone know how to get it out? or if its even possible?

Cheers. JM
