All you need for a 12" upgrade is the caliper bracket and rotors. I just spent this morning at the yard and did the upgrad on the 99 GT they had in the yard just to make sure everything fit. You will use your same calipers and pads.

Here's the list (thanks to Matt5112) of vehicles that have the caliper bracket for 12" brakes:

00-05 Buick LeSabre
97-05 Buick Park Avenue
97-99 Buick Riviera
97-98 Buick Regency
97-05 Cadillac Deville
97-02 Cadillac Eldorado
98-02 Chevrolet Camaro (steal the calipers too!!!)
00-05 Chevrolet Impala
00-05 Chevrolet Monte Carlo
97-03 Oldsmobile Aurora
98-99 Oldsmobile Intrigue
00-05 Pontiac Bonneville
98-02 Pontiac Firebird (steal the calipers too!!!)

I'm going the 12" route as the yard had an 03 Impala , but I'm going to get the TDC rotors and pads and new caliper hardware (bolts, rubber boots, etc) just because. It'll be easy to do...just gotta wait on parts.

Oh, and the caliper bracket bolts are the same on both cars too.

I'll put up pics when I'm done.
