So, without digging on 1ZY1- SOLID PAINT, I'm looking at your front fenders and notice the white goes all the way up to the grill and it makes me believe the white was added later on. See pics below, the earlier trucks had the inner color bordered by a pinstripe on the leading edge of the front fender. The last few years of two-tone squares, maybe 88-91 but I'm not 100% sure about which specific years, had the inner color go to the grill and below the front side marker light.
