'62 Kick Panel Trim and Paint Code tag? Questions

[Brad54]

I've got what I THINK is the data tag off the kick panel of my '62 K10 project.
Is there a decoder anywhere?

It says GVW Rating is 5,600 LB... What's the correct rating for '62 K10

Trim is STD (Standard)
Paint is 508 A (What color is this?)
Wheel Base is 127

What's really throwing me is the engine HP ratings:
115 @ 3600 RPM (235 cu. in.)
130 @ 3800 RPM (261 cu. in.)
160 @ 4000 RPM (327 cu. in)

There's no listing for the 283.

Is there a paint code chart anywhere?

Thanks,
-Brad
