Be careful with the advice. One poster hit the nail on the head backspacing is key. I installed SSBC disc brakes which are reproductions of the factory four piston calipers and use the original smaller ball joints But you need OEM 10 inch front brake knuckles. With 7 inch wide US mags slotted discs which I believe are 3.75 inch backspacing and any tire larger than 195/60 R 15’s the front of the wheel with catch the lower roll on the fender. The disks make it worse because it pushes the wheel out another half inch.
