Correct flavor of black for my dash

I cant seem to find out the correct finish for my dash other than black. How much gloss, etc. As long as were talking black, what should the firewall and floor be painted. A PPG number would be great.
Thanks in advance
Matt

 

dash is semi-gloss black. Can use the same for the firewall too

 

Thanks George, floor pan
as well?

 

Same. I believe GM sells Chassis Black which is a semi-gloss product.
