How did the bolt get stripped? Someone put the wrong sized allen wrench in it.

That particular bolt doesn't attach to the sub frame anywhere. It attaches to the engine arm. If your mount is degraded enough the rubber could deform in a way that this bolt moves a bit to one side or another.
What you can try to do is detach the two smaller upper allen bolts on both of your mounts so the engine is free of the subframe, then you'll use a very large strong screw driver or something along those lines to try and use some leverage to get the engine mount to budge a bit over in the direction you need to. It is the same process in reverse when you are done installing the new mounts and find your engine lowered just a bit to one side or another. It looks like this allen bolt is pretty stripped unfortunately. So getting it aligned will be your first challenge. Then you'll have to deal with getting the bolt extracted. They're in pretty tight. |

If it were mine, I'd drill off the bolt head in order to get the mount out. You'll probably find the remaining stub is fairly easy to twist out once the tension is off.

You could also try mig welding another bolt to it if you have room and as a side benefit it will heat the bolt and make it easier to remove.

Look in the DIY section; Members have driving a Torqx type bit into the Allen head hol and been able to turn the Bolt.
Then there is the already mentioned drilling. I am assuming you can get some sort of Pry Bar or piece of Wood in ther to shift the Engine around so the Bolt and Hole line up. It may be just lifting the Engine will allow the hole to line up. Also the Arm can be un-bolted from the Block.
