There are no direct fit replacements for those pickups. I replaced mine with some Bart P5 sized pickups, in fact, the ones linked in the first response to your post. The cavity had to be widened by 2-3mm and I have gaps at the ends. I filled the gaps with black epoxy putty. Pictures of my mods are in the BTB thread. The P6 size is closer across but I couldn't find a set that size for 5 strings. Here's a link to the thread, see post 650.
Clubs: BTB 118, Ibanez 689, 5-string 436, P&W 820, Lefties who play Rightie 157
BTB675, EDB605, GSR200, Ibanez Promethean 210, GK MB500, OB-110
