Would a 75 Duster front end kit fit my "updated" 68 Valiant?

A local guy has a Just Suspension front end kit for a 75 Duster for sale. I have a 68 Valiant, 9" brakes, SBP. I want to upgrade to the BBP and disc brakes someday(i need the BBP UCA's and spindles correct?). Will that kit fit when I convert it over? thanks
