Any downward force would be transfered very evenly with the mount. I believe the shear strength of the bolts does matter, unless you think the rear frame is going to rip off?

sounds like a "Jesus" bolt... Interesting, a frame that is behind rear diff... i wonder, what the purpose of it there... i need to pull out some of the blueprints, see what it does...
