Ok, i was shopping for nut replacement for Warmoth neck. They look like they should be Fender size 1 1/2 inches. Can i tell if the nut has curved bottom, or is flat with out removing it? Also, where can i get one, either tusq or bone, because Allparts and Musicians only have unshaped and unfiled, or shaped and pre-slotted. Warmoth does have the part, but charges a hardware minimum, making a 4 dollar part very expensive.
