The older ford axle from the 70's use a 5 bolt hole pattern on the knuckle to hold the spindle. TTB f150 axles use a 6 bolt pattern that is the same as used on jeep and chevy dana 44 axles.
On my waggoneer dana 44 I am using 1970s chevy knuckles, spindles off of early 70's jeep waggoneer, rotor and wheelbearings from an 89 f150, Caliper and caliper bracket is off an 80's jeep waggoneer. This setup uses an outer axle shaft off an 80's waggoneer and any dana 44 hubs (mine are off an 89 f150) Doing all this allows you to run histeer and a 5 on 5.5 bolt pattern.
Ball joints are teh same on all solid axle dana 44's I think the TTB are differnt but could be wrong.
The only part of my brake system that isnt new is the master cylinder, booster and hard lines. The truck stops strait and quick considering I am running a 35" tire much better then my old ranger with 33"s
