With the huge amount of feedback I received on my post here :-(, I was able to find what I was looking for.
(It was actually Kook's emails that helped me)
FYI, for those interested.
With all paints GM had, you can call DuPont.
Their number is 866-861-4569
They can find pretty much find any gm color. The color I was looking for is actually a '39 GM Color, so they said.
They cross referenced it with a Spectramaster code, which pretty much EVERY local paint shop carries.
My Spectramaster code for Ferrara Blue is BS456.
50 bucks for a quart of base, not bad.
Just an update, and good info for those that need it. . .
