The rotors recommended to you are the ones you need IF you have oem style 4 piston caliper Kelsey Hayes brakes.
You have to drift the studs out of your old set up and re-install your hubs into the new rotors.
I noticed you just joined FABO here and are maybe also new to mopars? Regardless I recommend you get a service manual for your car, they are even available on-line free on some models. This info would be in there for you.
Also do a search on these rotors on this website, lots of good info about the dust boots on the calipers rubbing and wearing out on the replacement rotors and what you can do about it to prevent that.
