I want to change out the studs on my 73 disks. They are press in correct? What diameter is the press in section? Do the 73 single piston caliper use banjos on the flex line? Mine have a banjo bolt threaded in where the li e should screw in. Not sure if someone used the banjo bolt to keep fluid in or what? What's the torque value on the castle nuts, upper balljoint, lower balljoint and tire rod ends? Thanks for your time.
