One thing that leads me to believe that the bracket might be stripped is that the bolt will pretty much just let me push it all the way up with my socket extension, turns freely as much as I feel like trying, and then pulls/falls right back out again.

So ... all your talk of sawzalls and cutting torches has me scared. Those bracket bolts must not be too easy to free, eh?

Maybe I am misunderstanding what you are saying but the threads are in the motor mount, not the arm.

the hole in the arm just allows the bolt to slip in, then you have to align it to thread into the motor mount.

The later ones screw into the arm from underneath, there is just a hole in the mount. W115 OM615 are from the top, don't know about the OM616.

Negative.

The threads are in the mount arm themselves. The rubber mount that rests on the body just has a hole in it in the middle for the bolt to pass through.

I had to get one side lined up and get it within about a turn of tight then had a helper with a five foot pipe pry the engine over about an inch and put some pretty good pressure on the pipe to hold it while I got the other bolt in and tightened them both. You may just not have the rubber mount hole aligned with the threads in the mount arm.
