Front suspension questions - big vs small bolt pattern

back in the day i used 72 or3 spindals big rotors and bolt patt.replaced upper arm too mine had baby ball joints drum car. and used new lower ball joints moog for dics brakes. all fit well but the new brake hoses took a differant frame mount. what the hose went threw. and if sway bar need to shorten the links the caliper hit on far left or right turn. i worked at a tire shop and had books and part to find out what fit. als
