Excellent job describing your interior color. Light or dark Pewter? clean NBS leather is hard to find because GM leather is shitty. Are you set on power/captians? If not I'd just do Katzkin or roadwire on a regular seat.
Very dark pewter would be your color. Katzkin and roadwire are leaps and bounds above OE "leather". I've had roadwire for 3+ years and love mine.Sorry for the late reply. But the interior is darker grey, and I thought about katzkinz. Think it would last better than gm leather?
