225 Four Barrel Exterior Emblems

He was selling several styles emblems at the Nationals last year at my space and the recommended procedure was to use the 3M double side emblem tape trimmed to fit. I believe silicone adhesive can be used as well. He's had his 345 emblems (commonly called a 5.7) on his Magnum for several years now - it's a daily driver in year round in MI - and has not had a problem with losing his emblems.
