Paint Mfgs. Who makes paint closest to the orig.

[Michael4yah]

Ive got a 2 Chevelles and a Camaro Im working on. I got all my codes and Mfg #s together and started calling around and I was amazed Not one supplier could get me:
1) AA Tuxedo Black, FF Marina Blue, KK Tripoli Turquoise.
I mean havnt these people seen the light?? There are a ton of prospective customers out there and all they can say is "Well this shade comes close or they dont make that anymore and without me supplying them with a chip they are lost!!! Hello!!!!!!!! You havnt seen the gazillion Chevelles painted Marina blue over the years????? Let me know how your quest for the right paint turned out.
