Advice in input shaft

Been reading posts and ntn 6500 lu or llu are suggested. Can’t seem to find any mention of them. Even on eBay. Any suggestions?
Also does Rodney have the new shafts available.
Some advice on best way to proceed.
Thanks

Forgot…did grant ever get the rebuild video posted. Loved the one he did…great info

Sorry I ended up having Rodney rebuild the transmission I took apart. So no I never made a follow up video.

I always got my input shafts from Rodney
