Upgrading to 11.75” discs on the front?

What are the correct calipers i need? I believe the ones i have are 79 volare calipers which are 2.75 pistons but from what im reading when you rear mount those calipers theres potential for the brake hoses binding or hitting the control arm? The calipers i have now are upside down because the hoses i had wouldnt work with the calipers right side up.
