Anyone heard of this? (ARTICLE)

It's basically saying these came with a D44 with 4:56 in many cases and can be added quite easily to a YJ, XJ, or TJ... the only issue being a 6 on 5.5 instead of a 5 on 5.5 bolt pattern.

I'm just curious if anyone knows anyone running this set up, or if you've heard urban legend about it.

It may be a better way to get a used D44 with 4:56 already set up, just add locker, etc...

Thanks.
