I used Schumacher mounts and Schumacher headers in 2 different builds 72 440 swinger and 70 440 Duster. Both had manual steering and brakes. One thing i noticed is, the header touched the passenger torsion bar (340 bars) but didnt touch on the Duster with bigger firm feel bars.. just had to cut a notch in the k member for the oil pump and used door shims to bring the engine up higher with a high volume pump. Easy swap for me. I could push the heater motor back to take the valve cover off too.
