I just bought a new overboost switchover valve for the 87 300D and want to make sure I got the right thing. Old part says 001 540 70 97, new one says 001 540 86 97. Only reason I ask is that there's another identical part closer to the blue vacuum dashpot and I want to make sure I didn't get that instead. I think I made it pretty clear which part I needed at the parts dept., but I always want to be sure. Can someone look up and see if 011 540 86 97 is the correct swithover valve?

Yes, 001 540 86 97 is the correct part.

Thanks speedy! I kind of figured it was, but always like to double-check. Got it all plugged in and screwed in place, so I'd be pretty bummed if I had gotten the wrong part.
