Rubicon U-Jonts - Full Circle Clips

I'm currently saving up for a PR44, but in the meantime I would like to upgrade my U-joints with full circle clips. Alloy USA X-Joints claim they drop into the factory Rubicon Dana 44 and show pictures of full circle clips. Can someone confirm if this is all I need to put full-circle clips and stronger joints on my front axle? Will I have to modify my front axles for the full circle clips? I've emailed Alloy USA with no response so far.

I haven't read into those specifically but I know every pair I looked at needed the ears grinded down to fit.

I have yet to see a set of factory axle shafts that can accept full circle clips without needing some grinding of the ears.

I think they say the x-joints are a drop-in replacement because they ship them with both full-circle and C-clips.
