Question on brake calipers

Hi Guys I just got a set of spindles to change out on my 82gt to the bigger 11" brakes. i need to get new calipers. what is the best way to go?

i have heard about the 87-88 mark vII calipers. i called the parts store and they have a steel piston caliper and the other caliper both are i belive he said 73cc pistons what ever they are they are the same excpt for the pistons. the steel piston ones are a bit more money.

i have also heard about the 82-82 continental calipers but never check on them.

last off i have also heard of a crown vic caliper with a police option. not sure on what years my guess would be late 80's.

i have a manual brake set up and want to get whats best. will thier be an issue with going with the biger calipers and fluid capisity on my master cylinder? i value everyones opion you guys have healped me out alot. please let me know i would like to do this swap quick

also to add I have a ranger manual master cyl. and am concerend about fluid capisity of the larger pistons callipers also added pedal effort. please let me know for my car with the 82 brakes and the manual brakes already had a lot of pedal effort. again thanks
