Silver Paint Question

So I'm gradually getting my car (8/73 240Z) back together after mixin' it up with some mailboxes back in April.

The car had been painted a darker than stock metallic silver and I'm pretty sure I won't be able to match the paint so I'm planning on having to shoot the entire car. I had assumed the color was 901 silver, but after peeling off the color code sticker (which was oversprayed with paint) enough of the paint came off to reveal a color code of #306.

My question is, has anyone seen this color next to 901, and if so, what are your thoughts and preference?
