Hey guys i was looking at getting a LSD centre for my single spinner diff. I have a late model 98 EL Falcon auto 4.0L.
First i was wanting to know if anyone would know how many spline the diff is (if thats the correct wording) im not too sure. Also what would be involved in doing the changeover, because i was told you may need different axles and some other parts
cheers

hey it is pretty much a straight swap out with the old in with the new

If you can, it's much easier if you swap the whole diff (rotor to rotor) assembly with the one you have. You can do that yourself if you're so inclined or if you can't swap centres out yourself.

just remember if you are changing centres, you will need a spreader and also possibly different shims.
