Alright, this is NOT about whether or not AM or any other store has good service.
BUT, now...I am a bit confused.
Swapping in new ring and pinion.
Bought the AM kit for 3.55's and got the requested upgraded bearing. ($50 option...)

Then saw that CJ jas the Ford M-4210-B2 kit AND it includes an updated rear pinion bearing that is heavier duty.

Latemodel has the kit that comes with the AM setup for 109.99 AND remarks at having that SAME bearing (GT500) included making it compatible with ALL 8.8 rear ends.

Is there a difference in the GT500 bearing and the one AM recommends? I ask because if they are the same, LMR is cheaper for a COMPLETE kit. Same fluids, gears and kit (assuming the LMR kit HAS that 50.00 bearing that AM recommends)
