Hornet interior trim piece needed..odd part?

["John W Rosa" <JohnRosa@xxxxxxxxxxxxxx>]

The blue Hornet I sold recently is in need of 'something'. 
Here's the scoop...you tell me the solution.

The car is a '73 originally with a tan interior. It currently 
has a windshield-mounted mirror that doesn't look 'stock' to 
me...but could be?

ANYWAY...the current BLACK LEVIS interior came from a '78 
Concord AMX...and the two pieces of plastic trim that go along 
the top of the windshield do NOT meet in the middle. There's a 
gap, and the end of each has a 'U' shaped notch as if the car 
had a mirror mounted between these pieces, at the center/top of 
the windshield....like my copper Hornet X has.

My quandry is this: The '78 catalog shows all 78s with a glass- 
mounted rear view mirror. So, is there a small 'filler' piece 
we're missing? Judging by this auction photo, there is-

If so, anyone got a spare of that small, rectangular piece... 
in black, preferably?

Or...

Can the glass-mounted mirror be removed leaving no trace or
is the windshield permanently scarred? And does anyone have 
an ealry frame-mounted mirror available out of a Hornet/Gremlin?

Reply direct if you've got either piece. Thanks.
