It's a two-piece cosmetic body panel with two sets of three horizontal slits above the headlight. It appears to also need a corresponding back-piece.

The larger of the two visible pieces was always painted. I am looking for this piece painted black (best), or primed (2d best), or any other color (acceptable 3d best). The other two pieces were always black unpainted plastic.

I am looking for this assembly to hide my East Coast's favorite $$$ toll collection device, the E-Z Pass transponder, within.

No need to hide your E-Z Fleece in the cockpit nacelle.  I attach mine to the inside of the tail cowl cover.  It's out of any weather, the sight of possible pilferers, and works great.

I have this. I sent you a PM.

Thank you... tried that, kind of. I run a top case on top of the cowling, and I have my E-Z Pass transponder inside the top case. Unfortunately, here in Virginia & Maryland, the E-Z Pass toll gantries and toll booths do pick up my E-Z Pass transporter in my top case, but intermittently and randomly. There is also, almost always, a time lag at toll booths (on-ramp & off-ramp) which is undesirable. Perhaps the various East Coast implementing states and cities have slightly differing transponder-reading equipment?

Besides, in chatting with someone here, I just realized that the plain-Jane K100 nacelle also hides two round horns behind those horizontal slits above the headloght. I already run two Fiamm Freeway Blaster coiled horns off a horn relay in front of the engine, so... can't ever have too many horns haha.

The orientation of the E-Z Fleece unit is very important.  I have found that the side with the Velcro has to face up to the E-Z Fleece readers above you or it won't work.  Attaching it inside the tail cowl cover puts it into the correct position and angle to be read.  Unless you have a very early brick with a steel seat pan, there is nothing in the way that will degrade the radio signal with that mounting location.

I have traveled a very large chunk of the U.S. and Canada with this setup, and have yet to have a problem.
