We have a 1984 1/2 FXRS original everything bike... including the ignition key. The key is showing some serious wear and despite mine and a skilled key makers best efforts, we are not able to find an alternative key blank that we can cut or even shave into a usable new key. The code on the key is C39. Not sure if I should be looking at antique shovelhead/Evo/Harley keys...any guidance would be great!
