The only kits I have seen from the usual suppliers all come with the Trans/transfer mout across the back. It is supported by two L shaped brackets that are welded to the frame, very similar to the front motor mounts that weld to the frame. On my sbc, I have the cast bellhousing form a 65-67 chev truck. It has the orginal mounting location on the botom corners. However there is a major clearnace problem with the front driveline to use these mounting position. I have seen a few custom bent tubing mounts on cruisers ,but they hung down pretty low to clear the driveshaft.
