IRS G series diff ratio help

[ed]

Pic of 4.88 crown on IRS centre. You will have problems meshing with the pinion if you put
4.88 crown and pinion into a IRS housing

it will work, but requires custom spacing

Yes you would need about 13mm spacer and then the crownwheel would not locate properly unless you welded the spacer to the crownwheel which would be a bit foolish

Hmmm, can anyone verify the 3.23?

The Group A centres were not all the same as far as i was aware . There were a few prototypes .
From what i found out 15 years ago they were a tall ratio on a TRD centre .
There was a bloke 2 suburbs from me in melbourne had a few of them for sale( prototypes maybe ) and i declined as they woulnt fit a F diff , stupid me.
There was one for sale in Brisbane on here a couple of years ago, i dont know who got that one . Some melb people that know the short Andy dude as he may have some more info on them . Anyone know where he is now
