On the Patrick's rear-end upgrade. Do you need to buy both the all ratio's ring & pinions and the ring & pinion installation kit?

What is the difference? Is one just the gears and the other include bearings, seals, and what-not?

The picture of the instalation kits shows it all. I was confused. I would also like to install this in my 53 - which will stay with the enclosed rear-end.

Thanks
