I have a '97 Fender American Deluxe 5 stringer with the 5 in 1 headstock, and diamond shaped tuners. I wish to change the diamond shaped tuners out with the deluxe clover tuners as used by Fender on 5 stringers in the late nineties/early 2000's. Can I purchase just the replacement tuner heads themselves, and change by unscrewing the old tuner parts and screwing on the new? You know, just replace the moving tuner itself and not the whole assembly? If so, where can I buy just the deluxe style tuner parts? Thanks in advance.
