I have that same rearend on my 2700 lb. nova. needless to say, it stops.

the problem you will find is that parts for that particular rearend are very hard to find... and expensive once you do. i finally found rotors and calipers and it cost me nearly $200 (with core). i also have been looking for rear brake hoses for weeks and no one has them. might have to re-use the ones that are on there.

Regardless, it will probably work for you, but parts might be hard to come by.
