i had the diff done by bernie, the gearbox was re-built ages ago by previous owner, as for driving better ...... hhmmmm
shall i say it drives different
if you want to drive it fast its awesome very sure footed, once you get used to the amount of grip the atb gives you and strange little movements of the back end as its getting grip. its awesome.
if sideways it your thing well still very good , except you need to 100% provoke it to go sideways otherwise it grips and grips and grips
But once it is sideways ..........

thats all ill say!!
