IF YOU HAVE A 1968AND EARLIER WITH NO BRAKE BOOSTER & Course Spline Inner Axles. THEN YOU WILL ALSO NEED THE FOLLOWING PARTS:

You need to dis-assemble the knuckles off of your FJ40. Get down to just the bare end of your axle. Then clean everything up, derust it, degrease them, paint the parts then start reassembly. You do not need to cut or modify your axle housing at all. You CAN re use your original booster & M/C just use the proportioning valve that we sell above. Early model axles from 6/75 and earlier will require some grinding of the lip at top and bottom of the inside ball to fit the birfields. Generally a 1/16" on top and bottom will suffice.
