I ended up ordering the tool.

 

where'd you get your tool from?

 

I bought it from here. A tad expensive and the thread was a little bit banged up at the end, but I could fix that myself:

bought it at a dealer for half that minus the shipping costs

 

Pics of where this bolt is would be appreciated.

 

It's the engine adjustment mounting bolt from what it sounds like.



See red circle. Number 22 on diagram.
You remove the outer nut, the long inner bolt, and the outer locking nut.
You will see the allen once the long inner through bolt is removed.
The allen bolt is wide and about 3-4 inches long. It pushes against a spacer between the frame and the engine, and is held in place by the through bolt and that allen bolt.

Doesn't make sense until you remove the through bolt.
I can take an actual picture later today of the bolt. Just don't feel like going to garage this early in the morning (for me).

Best idea is to remove it, take to hardware store and get a real bolt that matches the thread.

 

finally!!!! a real answer! thank you for at least shedding some light on to where this thing is

 

I've read this thread before but the description didn't make sense to me until recently, since I dropped the motor.
I had to pick up a large hex set to remove that bolt.
