Jason,

I am sure that it could be done, however it will not be an easy swap at all. You would need to fabricate ladder bar mounts as well as a panhard bar and mount on the chassis. Nothing will be a simple bolt in or even a simple fabricating job. If you have the resources it could be an option, but if you aren't or don't have access to a good weldor/fabricator you might want to look for a standard Chevelle rearend.

The easiest swap that I have seen that is similar to what you are suggesting is the Truckarm setup from Hotrods to Hell Centerdrive (http://www.hotrodstohell.net/truckarm/truckarm_index.htm).

Good Luck.
