Air locker help

[Craigmorley]

Right looking to buy an air locker for my 2.4lj70 1992 model but I'm unsure which one as don't no how many splines and how many bolts I have??
I don't want to take apart to look as I use it everyday so has anyone got any ideas? Thanks

When I got mine I just called Devon 4x4, told them I wanted an ARB air locker for a 1993 LJ70 and they ordered me one, there was no counting splines or bolts!

The only slight issue I had was that the fitting a front one requires changing the bearings to 50mm ones, but it has the sizes and part numbers in the ARB instructions.

I'd definitely recommend Devon 4x4, I've used them a few times and have always been happy with the service and price.
