You mean something along these lines?
stronger ball joints
high steer for less $$$
added tube strength (if you sleeve the whole tube)
welding required (for some)
wheel bolt pattern changes
I have in axles:
$60 for a waggy 44 (flat tops, spindles, brakes)
$50 for ford hubs and rotors
$100 for the XJ 30
-$10 for the cj 30 :tonka:
Plus high steer arms and machining for ~$200.
Add a super 30 inners and locker and be really close to 44 strength, I am gonna run stock shafts for now and see how they hold up
