Putting emblems on

those little white plastic sleeves are what the factory used......those nuts will work if you can get to the backside of panel to put them on.....Just a tip.....if you have the factory size holes in the panel, I have used a piece of air line tubing the right size in place of those plastic sleeves and they work great also.....forget off the top of my head but maybe 1/4 inch tubing????
