Questions on BBP upgrade on '67-'72

I'm preparing to do a big bolt pattern upgrade on a '67 A body. It's been 20 years since I did one of these upgrades, so I'm a little foggy.

I am running a '68 K member (for improved idler arm design), Doctor Diff reproduction knuckles, a stock sway bar with stock LCAs with stock sway bar tabs, 10.95 rotors and 14"x5.5" steel wheels.

With this setup, do I want to run the calipers on the front or back?
