    Depends on the engine. 6cyl and 4.2 were a small salisbury, basically a banjo in disguise. 23 spline, could be LSD. 5.0L used a large salisbury (same centre as HQ-WB V8). These are 28 spline and also optional in LSD.

    correcto...but the large Salisbury (only with LSD)
    was also an option on both 6 and 253 versions
    (and I know there were some built)

    Yeah, that's right. I forgot that the 10-bolt was LSD only in Commodore.

    I knew that the VB rally cars had 10-bolts, I never knew they were optional on mainstream 6cyl and 253. Learn something new every day.

    Small sals had discs, std on V8. If it was originally a 253 it'd be almost certainly a baby salisbury.

    To 10 bolt LSD imo wont be a long term solution. Next step is a Borg Warner BW78 diff which was fitted to late VL V8 and 6cylinder turbos but slightly wider(approx 6mm per side) than the Salisbury diffs. The advantage over the Salisbury is the BW78(78=7.8inch crown) is stronger, more parts available as standard fitment from VN-VS, Skylines, some Falcons(not my forte as to which) and others. The axles are 28 spline and centre is 4-pinion. You can fit the VN-VS variant to a VK but it will be an inch wider than the Salisbury either side.
    The BW78 will not be as strong as a nine inch, but weighs a heap less, other advantage is you can use factory tailshaft or the rear half to complete conversion using V8 front shaft.
    Nine inch is the ducks guts, but weighs a ton, needs to built by a reputable shop as you could have out of square housings, weak axle ends if not shortened properly, and if you go single piece tailshaft, you have to mod floorpan to accommodate. The 9 inch i had had the pinion exactly centre where the salisbury looked offset, and from memory the floorpan had the sal in mind, but dont quote me on that line as it was a few years ago. All other info can be 2nded by any Commodore guru...
