Well, the meet was a big success for me. I have a new rear diff! Big thanks to Adam, who basically single-handedly replaced my diff! Also thanks to Archie and Taylor for lending a hand.
Haven't bled the AYC yet, and must say I've noticed a big difference with it not active, handles like a pig. For those who were there - Hamish from Evoscan is still working out a few niggles with AYC and is planning a new release shortly. Seems some AYC versions are not compatible yet. Have to bleed it this weekend on stands I think, as Donnithorne want $83 +gst +oil costs to bleed it and I don't have that money at the moment.
Thanks everyone!
