If you retain the stock bellhousing (and it's associated dog-ear bell housing mounts), then you should not use a trans tail-housing crossmember. Only 2 mount locations should be used along the engine/trans driveline combo - not 3. (I'm counting both bell mounts as "1" and the engine mounts as "1").

This question comes up every once in a while and it's a good question - but if you note that newer vehicles that have rear trans crossmembers don't have bell housing mounts, it starts to make sense. Overall reason has to do with potential flexing, or resisting of flexing as a unit, etc of the engine/trans combo - so only 2 mount locations needed or deisred. Either Engine+bell, or Engine+trans rear crossmember.
