Patches and discussion for Ensoniq VFX family

Hi.  I'm looking for lowest C key to replace broken one.
Please help me to find it.....I know Keyboard part was made by FATAR.
I called FATAR and they couldn't help.  They told me to call Ensoniq.....So I called 
Ensoniq......They said they don't have any replacement parts for their old keyboards.
Now what can I do.........Any idea?????       Please help!!!!
I love my VFX and I don't want to see myVFX like that......

Thank you very much
