The lads above have it right, you must buy the ring and pinion as a matched/lapped set, and after counting teeth in my RA23 diff centre, its a 41/10 combination for a final drive ratio of 4.100 exactly.
Now, if you like working parts miracles, here is one for you. Search all your import yards and wreckers for a grey import YM40 Liteace van, and you need it to be 4WD and in a manual (only). They have a front (yes - front, and the rear is an E or F series diff) differential ratio of 4.3:1 (43/10) and 6.7 inch ring gear diameter, making it a 'T' series diff, in a manner of speaking.
You won't be able to use the housing, but the internals of this will fit your RA23/28 diff housing.
I learned this from a kiwi friend who said that this swap has been done successfully in NZ for some time now.
And yes, good luck - goes without saying really.
Mitch.
