Well, its about £60 and alot cheaper than Westfield's offering. They say it is a drop in replacement for the ball section that lengthens the lever under the fulcrum point (the ball) - exactly what I was on about. The stick is a separate piece held in place with a split pin. I'll still need to shorten it though, but I think I can tackle that.

I will document it on my build site.

Pass me the ANGLE GRINDER!!!!!
