DIFFERENTIALS..or diffs

Couple of fixes:

The "mythical" A9X ratio 10 bolt was 3.90:1.

3.90:1 banjo was optional on some Holden 6cyl, at least for HK-HQ. Not sure about exactly which models and series.

byron thats not what the race car guys say..but they are old and may be mixing up there numbers..

3.90 banjo was optional in utes and vans from books ive seen and also standard in 4 cyl lx torana..then the 3.9 crown and pinnion was used in the uc 4 cylinders.

Okay, one question for you...

This diff is a "Small" salisbury from a 6cyl WB built 4/80.



Why does it have holes in the ears??? is it the holes for the bushes???

and then this is also a "Small" salisbury from a WB built 8/83, this one has no holes in the ears.

the centre is a cast unit and the axle housings were pressed into it so if they had no non holed ear centres for ute/van they would use whatever they had..that centre could have been used in uc torana or vb commodore...holden didnt stop the production line coz they ran out of something particular..

The one with no holes is a ute diff, the one with holes is sedan diff. You can convert a sedan diff housing by welding on the leaf spring brackets.

correct in principle but they didnt have small salisburys in wb sedans..see above explanation..

Pull the inspection plate and my sedan 10 bolt that is modified to fit my van must have had the centre changed as well as it is a 3.08 centre and not 2.60 2.78 which are usually a car type ratio
