New Dana 60 Help please

Hey guys so I have this kit.

Right Stuff Detailing MDCRDM1 Mopar Rear Disc Conversion https://www.amazon.com/dp/B009NRB988/?tag=fabo03-20

What would I need to make it work with this Dana 60HD?

The current studs don't match up with the bolt pattern and I'm getting rotors confused with disc brakes that already have the studs in them already?

You need to figure out what that kit is designed for and then see if those parts will work with the rear end you have. There are different housing ends that can be used and there are different axle stand off dimensions that are used. You can't just buy random parts and expect them to work together. There are certain combinations of parts that work together but other parts don't work.

I use the Ford Torino housing ends on my cars since there are a lot of brake kits that fit the Torino housing ends. But when you use the Torino ends you have to know which bearings to use and what the hub standoff will be and lot of other details.
