Sources for '57 Chevy paint?

I'm starting a resto job on a '57 Bel Air. He wants to go with the Tropical Turquoiose and India Ivory.

I'm looking for companies with formulas for single stage urethanes. Can anyone help?

PPG paint . they should have it on file if you call them

Thats what I used on my wifes 57 PPG but watch them when they look up the numbers I wound up with a gal of sea foam green . They made good on it but I guess the numbers are close. http://57classicchevy.com/body-colors.html

get it in prospray .

Check Matrix if you have a local independent dealer. Exact same codes and formulae as PPG at about 1/2 the cost.

And another source, they do PPG; http://www.tcpglobal.com/autocolorlibrary/

Thanks guys, I haven't made a decision yet. So far I also found that Nason, and Sherwin Williams do early colors in single stage.
