Outer Limits 4x4 Board

I did a search and also asked our local ARB agent the following question. Is there a difference between the spools and or shafts on the GQ diffs between the LSD and the factory locker? ARB state the same diff for the H233B, be it with the LSD or with the factory locker. A mate put a ARB into the diff with the factory locker and he reckons the one side shaft is too long to fit. Another mate put the same ARB into a LS diff and he reckons the shaft only goes into the locker by 15mm. Are these guys installing wrong or is there actually a difference in the shaft length and or spool dimensions?

there is a difference in the shaft lengths, its like the centre piont is more one way on the vac locker then the lsd but only about 6mm

Cheers thanks. Is the fact that the shaft on the vac locker is shorter a problem. I mean if it does not stick in so far have guys been twisting the end off or stripping splines?

should be no problem at all its only 6mm or so, I did measure it a few years back but thats about all it will be
