need help.. lower balljoint

The parts #'s are correct for a 72 Dart w/ disc brakes. Can you use the old bolts ?

no the bolts are to big won't go through the holes


what disc brakes are you using? 72 would be the 4 piston and small bolt and uses the smaller ball joint i believe. 73-up big bolt ises a single piston and a larger ball joint.
