There are a few good threads on this subject here and on the 67-72 forum. Width of the '84 will be something to check, and you will also have to convert it to work with coil springs, its likely a leaf sprung rear end.

You can buy the coil spring mounts and weld them to it, but may be easier to find a 71 or 72 rear end thats coil spring and 5 lug.
