I have a 2012 MIM FSR Jazz and the pickups are the standard dissimilar sizes as US Jazz basses. I'm not sure what year they switched, but I was told that later MIM jazzes are this way.
The stock Pickups on mine are a little anemic. After reading the stickies and posts, I decided on a set of DiMarzio Area J pickups. They seem to be the best fit of output, vintage tone, hum canceling and price. They should be in shortly! I like everything else about this bass.
Can't help with the bridge replacement though.
