Relocated to a hidden spot.
Seriously...it is a mystery. I had an '86, and it looked like it had been in the lower, left hand kick panel. It's also AWAL in the '85, and I think Jim's '86 as well. I kick myself for not tracking it down in my '86 before I sold it, and I haven't looked in the '85.
Jim is on the road still, but he may have more to offer when he gets home. In the meantime, I'll take a look at pics of his '86 (and the '85) and see if I can come up with anything else. Whatever the deal is, it looks like it was something that FHP requested when they ordered the cars.
