Cool, perhaps you could you put a link to Tonys info, im sure it will be usefull for others who discover this thread, and are wanting to do the job starting from scratch ?
Or......Maybe Tony just needs to fit one in my rig, only so i can take detailed pics from the start, all the way through

(ha-ha)
Would also be interested if you could measure your approx turning circle when locked in 4wd with your open centre now (obviously need to be on grass, dirt or sand etc), so it can be compared after lokka install.
I also assume you have manual hubs ?, im interested to get the chance to confirm/dismiss the auto hub problems when used with lokkas (ive heard mixed reports about UN-locking issues)
