Ok guys, so I'm putting my '74 back together. The car had vinyl on it, and the trim that goes of the bottom of the vinyl (see picture) is wider than the trim on my brother's '70.
Mine is also held on with rivets and a slide lock thingie (my dad said his '70 had this too) but my brother's doesn't. His trim is held on by a little clip that pops into a hole in the body. When you want to remover his you just squeeze the clip and it pops out. Sorry I don't have any pictures of his, but are both of ours stock trim?
