Help! Need info on 8 3/4 brakes

Hi,I have a 66 dart gt w/ 7 1/4 rear end. I bought an 8 3/4 housing w/ backing plates & axles and brake drums It is the small bolt pattern. I need all the parts for the brakes. ie, shoes, springs, wheel cylinders, everything.. Is there somewhere I can buy a kit w/everything I need or am I going to have to buy piece by piece??? and if so, does anyone know where I can find the complete list of everything i need??? Thanking you in advance, John
