The mount is also attached at the bottom via two bolts. The auto mount I just got is not shaped to accept the middle bolt so I assume it does not matter.
I'm not sure what is what from your description, but the bottom line is to use a stick rear tranny mount and make sure your ds is really straight with no abrupt kinks in it.
