need new u joints for mog axles but not really shure what model they are [ 404, 406 ] the front and rear are the same [rear steer]. theres no tag how can i tell what what model they are and where can i find the u joints? thanks.

Try Expedition Imports...

is it a one piece axle case with the diff as a third member(early 411/404) or is it a three piece case where the axle tubes bolt to the diff center(later 411 upwards)

they are the 3 piece style. didnt see the same axles on expeditions site.

Probably 406/416. Best bet would be to call EI.
