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.

Upside down calipers is a bad plan since you won't be able to bleed them. Doctor Diff sells calipers with dual bleeders so they can be mounted in any location. That is a very simple and very clever solution.
