correct color of a '70 B.B. Camaro tail panel?

[CamarosRus]

I do own a 70 L-78 Camaro with mostly original paint. Car needs resto and eventually will get FULL everything.
I've been following the above subject with much interest for years.
I've never read, seen or heard of an accurate paint company code for the tailpanel black. After seeing BKH's Yenko that went to Charley I could SEE how Glossy they were. Most people go way too flat versus, a quite glossy semi-gloss.
There was also a low milage original paint Garnet Red 69 L-78 at Carlisle (yr ??) owned by Jeff Boone from PA. Hopefully readers here can attest to its gloss....
See my 70 L-78 Tailpanel below, and look in corner around license plate for gloss!!!
