Yay more turquoise!
My 69 Chev C20 was a White-Turquoise/Turquoise combo originally too.
It will be a while as I'm getting the mechanical stuff done first before the body resto, but I'm going with a stock style two tone, but with white/aqua blue metallic from the 2010 Camaro, with a black/turquoise interior. Most of my turquoise interior pieces need replacing so I'm going two toned.
