Is there a Place to get replacement stickers for the door jambs. of all 3 G's I have none of them are legible any more. The only thing I can read off one door is that one sticker is Tire Load information, the other says something about Manufactured by General Motors. Then my GP also has a Canada Transport NSUAC CMVSS sticker. I really don't know where to start looking for these. Is this something where I have to contact GM Hitsorical to get it?
