Sorry to answer your question with a question but I'd like to comment or ask about on the SPID you show in your photo..

Mine is a '70 as well and my SPID looks and is even worded differently for the same options..

I have read there were repro SPID decals available but have never seen one.. either yours or mine might be one of those..

Mine is a Fremont Ca truck; so maybe that is why they differ; but here is a photo..

Your color scheme sounds cool though - obviously sounds like a two tone but a rare combination.
