VERY IMPORTANT...

These drive units are NOT a direct drop in replacement. The original basket size was slightly greater in diameter, so you will need some DIY skill to mount these in the cabinet. Two methods have been used though, centring the driver and refitting woodscrews if there is enough wood available and the other way involves cutting the basket edge to make tabs for mounting.
