VL LSD diff conversion

[05 Senator]

Hey guys, sorry to make another diff thread but but i cant find what im looking for.
I was wondering if i can just buy an lsd diff centre and put in my VL calais. apparently its just a standard diff with 3.9:1 gears.
ive found a couple of LSD diff centres on ebay but i dont know if it will work.
4 Pinion 28 spline LSD aka 'VL Turbo' Diff Centre - eBay V8, Performance Parts, Car Parts, Accessories, Cars, Bikes, Boats. (end time 29-Jul-10 23:22:07 AEST)
its a 28 spline 4 pinion but im pretty sure mines just the 25 spline 2 pinion. is it easier to buy a complete lsd diff? cheers guys

if you have a 25 spline diff you will need to change axles as they wont fit the 28spline diff centre.

ok so how do i tell if i need long or short axles. i would imagine if its standard id need the long axles yeah? i found some for $700 brand new. includes bearings and studs. is this worth that much?
