Yet another interior paint color question

['68 C-20]

I have searched these forums, here and at Paint and Body Forums. If this is redundant please bear with me,

Also, I have been to the Auto Color Library and pulled the Paint Chips. Problem is that the interior colors are a bit ambiguous and there are no chips to reference.

I am trying to figure out the interior paint color on my '68 C20. First off it is Blue. The Exterior is Dark Blue, Glove box sticker indicates 4508AA, looks like a PPG 508, Glove box indicates 4614J8 Blue Vinyl Trim. Not sure what that equates to for a dye, but I don't need to dye it anyway.

The first question is the blue interior color on the Floor, Dash, Radio Cover Kick Panels , Roof etc. It appears to be a light blue, probably a metallic, I would put it perhaps at Turquoise. Anyone know the PPG color or equivalent?

Second question, The Steel Door Panels are Dark Blue, looks like a Poly or fine metallic which is a bit odd since the Body is not a metallic paint. But it is quite close to the exterior color, just in a metallic.. Anyone run into this? Know what color the door panels are?

I am highly confident that nothing has been repainted. It is as came from the Factory.

I want to two tone the body and use the metallic dark blue on the inside door panels for the dark parts and the light blue interior color for light parts.
