I am trying to remove my starter motor. It died on me...

I am having a hell of a time with the top bolt.  Is there a trick to
it.  Would I get to it easier if I removed the air filter and pipes
leading to it?

On a side note, someone broke into my van over the weekend.  They broke
the passenger side rear most window.  Glass is everywhere, even in the
water tank, which I leave open for the winter.  Glass is on the bed
etc.  What is the best way to get this out.  I certainly don't want to
sleep or drink glass this summer.
