You are going to need new spindles, front brakes/drums, 5 lug wheels, coil springs and a center link as well as the tie rod ends and idle arm that you have in the picture. It would be advisable to replace the upper ball joints, upper arm shafts and lower arm/ball joint. The bad news is you need a Falcon V8 steering box and cannot use a Mustang box, different length of shafts. It goes on as you will need a Falcon V8 drive shaft but can use a Mustang 8 inch rear axle.
