I recently purchaced a second truck. A 67 K10 lwb. The truck has been repainted silver but is light blue underneath. The paint code on the glove box sticker says 455AD which I believe is an RPO code but can find no reference to. On the firewall in grease pencil there is 537 written. I found that this is for two tone light blue/ivory. What is the difference, I cannot find any paint codes that are 400 numbers.

Does anyone know a link to RPO codes? Where is the two tone split on a 67? Is is split below the rear window?

Thank you but ,I have found that site before on the internet and it does not show two toned colors or any of the numbers I am looking for in 66,67 or 68. I did print a sheet (dont rember where) that is a Rinshed- Mason products for 1967 chevy truck colors. It shows both 14 solid colors and 13 two toned color combinations. It only refrences the 3 digit, 500 codes not the 5 digit code on my glove box. Also I noticed that the 1967 restoration packet refrences to see the "cabs, bodies and colors section" which I cannot find in my packet.
