THanks for putting up those pics PIGDOG, its about time I finished this thread. Although I have not yet done the hand brake cable I am working on it. I got all the hand brake bits off the R31 skyline and am currently looking at adapting it to my ute.
On another note I sent a hand brake question off to Mad Dat Motorsport and they are working on a addaptor/hand brake set up for those who have fitted a R31 diff to a datto. Within the next few weeks was their guess as to when one might be available.
