I'll wait until I see it till I believe it. I'd still be pretty certain that Q2 differential (part number 0055208952) doesn't fit the gearbox of a Brera/Spider/159 as it is different from the gearbox fitted to 156/147/GT/GTV/166 etc.. The Q2 doesn't fit the 6-speed box in the 156 2.4 JTD 20V either for exactly the same reason - totally different gearbox, and that car isn't listed on the Jamie Porter website..
