Anyone got pics of their transmission mount?

I am building the crossmember from subframe connector to subframe connector in my 1970 Dart with a 5.7 hemi, 545rfe trans. Everything is lining up perfectly and I am using a polyurethane transmission mount. My question is, are you guys using the three mounting points from the original transmission mounts (red arrows and yellow) or just the front two trans mount holes (red arrows). The factory mounted all 3. I am not sure if that would be overkill, or if it supports the tail shaft and needs the support.
Anyone got thoughts on this and/or pictures of your tranny cross members?
