Thanks for the paint pics, that does look very very close.
I did find a "Dark Metallic Fawn" that looks close to what I'm looking for on my 68 and for the price, I ordered and am going to try.

Also going to a local autobody paint supply house and seeing what they can come up with for "Silver Fawn Poly 23026" that is listed in the table below.
I find it 'interesting' that the 68 color chart above calls DARK FAWN
POLY 22862 , where in the color chip table (that I posted above) it calls DARK FAWN (Flat) the same# 22862. I realize it's the sheen, but anyway...
