Good question mate......It definitely helped seeing it in white before the resto....
I was 50/50 at one stage going back to B5 Blue, but in the end followed my heart, not correctness.
I only gave B5 Blue a thought because it was correct, but down here in New Zealand no one gives two craps. lol
I'd say yes I would have painted it white (PW7) love white and have owned 3 different white cars.
Black would be my second choice and for a 70 Cuda I couldn't go past Limelight.....
