I think you can still buy the letters, but it is a complete set. Cost was $85.00/set, but I think I remember someone paying $125.00 for a set.

Forum members send their letter they have removed and I clean them and put new adhesive on them and send them out for free. I just ask that they check what is still on the car and repair/new adhesive ,so they don't lose anymore. The letters are getting harder to find.

I found a supply that makes letters, but they are not the same as OEM. you would need to changes all the letters as they are not the same. They cost about $40.00 for a set.
