Unfortunately,I don't have the letter :"F" as that was the one I had to replace on our Crossfire. Crossfire Accessories and more used to stock sets of letters: http://www.crossfireaccessoriesandmore.com. The set I purchased came from ebay: Using the keywords Chrysler Crossfire letters, I came up with the following: https://www.ebay.com/sch/i.html?_fro...tters&_sacat=0
The letters I ended up with did not have the chromed silver on the sides of the letters, just the top surface, I had to buy a spray can and spray on the silver to match the car's letters before I applied it to the car. Good luck!
