Dana 60 rear brake kit?

i swapped my rear end from an 8 1/4 to a dana 60 and am needing a new brake set up. i am wondering what i need to do both disc or drum brakes and what i can use thats already on my 72 demon. i already have a conversion done on the front and have a new master cylinder for it installed. the dana is 5 x 4.5 and is a 2.5 offset. any help would be really appreciated. i was looking at this set up but am not sure if it is what i need. http://www.summitracing.com/parts/wil-140-10767-dr
