Andersons in QLD had a set a while back, also Macnamara Diffs in Melb used to do a conversion I do not Know if they still do. If no luck try fitting the 1.113 until you find a set. Iwas talking to a mate the other day he was using the 1.113 gears behind a very strong 383 chev and found they ran at around 140-160C compared to 240C with the 0.996 gears
