That is correct, early ADs had pinstripes on the grille bars. And I believe all pickups had the beltline pinstripe, now if it was 1/8 or 1/4 inch, well, that has been discussed a lot, but I still believe the Chevrolet plan was 1/4 inch, despite the fact it seems some factorys made it 1/8. I found a set of original wheels and those stripes were 1/4 inch also.
