Kind of dumb to ask for but...
A few weekends ago I took off the instrument cluster of my K75 and opened it up to calibrate the speedometer using Drake's directions. It seems I pulled on the trip odometer knob too hard when putting it back together because the hardware behind it (spring, couple washers, and who knows what else) blew across the apartment, never to be found again (I searched).
The knob itself stayed in the side of the cluster and was still able to reset the trip odometer but today I noticed that it fell out on the road somewhere.
So again, it seems dumb to ask, but I need the knob and the hardware that goes behind it inside the cluster. I figured it'd be worth posting...
