I know this has been probably asked before but I have gone from a 3.76 diff to a 3.1
With 10" wheels and the motor is an aussie 998 is there a correct gear set available for this diff ratio ?

You need a 7/16 according to the Guessworks calculator (http://www.guess-works.com/Tech/ratio.htm) assuming a 1408 TPM speedo (850/deluxe/mini k).

Guessworks have the 16t as a new part, and usually have the 7t used, but this is shown as out of stock currently.

7t: http://www.guess-works.com/Shop/Parts/d ... htm?id=326
