I do custom crossmembers on all the Atlas installs. That is the only way I can generally get them in place with the stock transmission mount to slow down the potential for annoying vibes at idle. I also use my "custom" belly skids. Custom in quotes since I do have the plates cut and bent up in small batches but I do have to fit each one to the frame holes for the bolts.
I wish I would have done a crossmember mount then found the correct skid for the height I could get out of it. Instead of hitting the easy button. Factory rubber mounts are a must for me too.
