So I feel kind of silly asking this having already completely dissambled my D-60, but I'm going to get a lock right for it and I'm wondering...
Currently I have 4.10 gears, I'm going to 4.56, so does the lock right replace the carrier like a detroit does? And if it doesn't do I have to buy a 4.56 carrier? and then gears, and then the lock right?

The carrier is out anyway, might as well 

And yes no need to touch the ring and pinion when installing!!
