This is not a bulk buy or a sale.....so I am not sure where this thread really belongs but here goes.
Recently I contacted Quaife about buying one of their QDF6F ATB diff's for the G series gearbox : Mazda 626 FWD Quaife ATB Helical LSD differential - Quaife Engineering
And the response I got was "we just sold the last one and we wont do another run until we get 10 orders".
its a bit of a long shot..but if your in the market for one it'd be worth while for everyone to place orders with Quaife so that we all get one.
Alternately if there isn't much interest, and anyone has one that theyre not using and want to sell, PM me of the list.
