i am doing a rear disk conversion on my 14 bolt and one of the calipers i was going to use has a ripped boot, since i am gonna buy new calipers i was looking for some input on what size piston to go with, the ones i had have around a 3 inch piston, but there is a 2-5/8th piston caliper. im thinking about going with the smaller piston because i am still useing the stock brake setup and they do not hold a lot of fluid. keep in mind i have a 60 in the front

Rear brakes only do 30% of the braking and its a chevy 3/4 ton caliper they use I believe

u need 3/4 rotors and calipers, there is just a couple different choices for calipers, i have everything done, just need to decide on what cailpers im gonna use, i dont want to stress the master cylinder and brake booster more than it already is having the big calipers up front already, so i was thinking of going with the smaller piston calipers in the back. how well it will work, i do not know ??

I'm using a 3/4 ton rear caliper on my f2fiddy, upgrade the proportioning valve from a newer chev gasser with rear disks

Are they using a driveline brake?

i never looked or asked, but i know one guys have a switch on the dash and it works as an e brake, im guessing its a line lock but not too sure, i can find out tho

Line lock for ebrake and can normally be kept street legal

line lock is borderline legal, same with driveline e-brakes,
