Ok here's the mod on the front grill and final placement - now it looks more acceptable. To normal people (meaning non enthusiasts), it's all but invisible.
So with fiskars/pruning shears, I cut a notch for the sensor to fit back in the grill - alcohol wipe, VHB stick and adjust angle:
Nestled in nicely - no part of grill shows the cuts, if you are not OCD....
And now a clean look now:
by the way, there is a pic somewhere on the web with the sensor mounted on a C7 under the top grill piece with sensor seeing straight ahead - that won't work picking up ingots and such, just walls ahead of you..and if you can't see a wall ahead of you, you've got bigger problems that what this device shows you...LOL....It has to angle 45 degree down.
