Thanks guys! I was just a little concerned with using a 4 point mount system. The 6's torque moves things around and I didn't want to set up anything that was causing undue stress on the mounting flanges. A friend who builds and races modifieds mentioned that they used solid motor mounts and just left the aluminum Muncie (I think) hang out unsupported. He said the only time they had a problem was when an engine or diff let go. Think I'll go ahead and fab a crossmember just to be safe. (conventional)
Thanks again.
