I'm using Tom's kit on my 56 truck rear end (67 Camaro 12bolt)
The kit was good and you get most everything but the instructions are lame at best. As long as you are experienced in suspension and brake work you will know about residual valves and using a disc brake master cylinder and related parts needed. They don't supply nor do they tell you what else is required to complete the kit, you are just getting those parts pictured...
BTW the rear calipers are 80 Cadillac Seville rear calipers, he reason I know is I received 2 driver sides instead of a passenger side. I had to exchange it locally.
All in all its on and works as expected....here are some pictures...good luck
