crankshaft position sensor for 91 560SEL

[emmydotnet]

I am trying to diagnose a hard start when warm and intermittent rough idle. I suspect it is the crank position sensor. Upon inspection, I found that the cable of the sensor installed appears to be like a 0021533428 because it has the metal bracket that is used to mount the cable onto the left side of the head. Browsing for the crank sensor for a 560SEL, P/N 0021534628 is showing up and basing on the pictures, it does not look like there is a metal mounting bracket. Can someone confirm what is the correct part number for a 91 560SEL? Do I have the wrong sensor installed based on the sensor having the metal mounting bracket?

Thank you
