It is the same box - it has the electronics built into it to recieve input from the Servotronic system - but since I have no Servotronic - It just operates as the normal Steering box.

The 540 Steering boxes in the US were different than the US Spec 535/535 Rack and Pinion steering boxes. BMW had to use the different Box due to the fact that the rack and pinion boxes would not clear the V-8 motors. Hope this helps if at all - JT
Yeah, I read that in your other thread. Still waiting to hear back from that ebay seller you listed, to see if that's one of his ~$400 remanufactured units are a possibility.
