I havent recieved my JB/59 for my tokai yet

so i dunno how big the pickups are.
i kinda want to take the pickups out of the tokai to make sure they are stock, but i have no experience and very limited knowledge about pickup swaps. last time i soldered was 6 years ago? and i dont have a multimeter.
I'm a duncan kinda guy, cuz im a mahogany kinda guy.
debating going whole hog and BKP'ing at least the bridge of the C7..or i should wait till i get a custom guitar hahahahaha
