***SOLD*****F/S: one set of 345 Hemi emblems. These are high quality emblems. They are not the cheap plastic ones. I paid $180 new. Selling for $125 + S&H USPS Priority (about $13.00). PM if interested.
They are billet. Yes, they hold on with double sided tape. They were very hard to remove, so once they're on, they're on. Do a search for coppergenius. These are very high quality, custom made. PM if interested.
