BMW 335 transmission oil cooler

Burger Motorsports transmission cooler to suit E9x BMW 335 models with either 6 speed automatic or 7 speed DCT. Brand new. I bought it for my BMW Z4 35i and tried to install it but it doesnt fit - the cooler is too big for the Z4 cavity. Replacement cost is over AU$700. Collect from Felixstow (SA) or post at buyers expense.
