Source for 5 and 6 strings Jazzbass closed covers

[EtLa]

Does anyone know a source for Jazzbass covers without holes. I'm looking for 5 and 6 strings length covers.

I'm looking for closed jazz bass and precision bass cover, with no luck.

I need them badly, and guitarjones doesn't seem to have the closed ones.

Guitarjones has closed covers listed, and I've gotten some closed Jazz covers from him. He used to list 5 string covers and bobbins. I'm sure he can order them if you ask.

I don't know of anyone who makes 6 string jazz covers. Do people even make 6 string Jazz pickups?
