Thunderbird ‘3.9’ Chrome Numbering Set – – New Product! – Show the world what’s under your Thunderbird’s hood with our new ‘3.9’ lettering set. All 2002-2005 Thunderbirds feature the 3.9 liter V8 engine, but Ford never included any exterior badging to show it. Now you can display your Thunderbird’s impressive power with this lettering set. Measuring approximately 1.5″ high and 1 .2″ wide, our letters are triple chrome-plated ABS plastic, guaranteed not to fade or tarnish! Installs quickly and easily using the attached 3M automotive adhesive. No cutting or drilling required! The set includes six pieces and look great on your front fenders under the louver vents, on your hood scoop, or on your rear fenders under the ‘Thunderbird’ script lettering. A great addition to any 2002-2005 Thunderbird and is an ideal complement to our ‘Y Block’ emblem (sold separately).
