Home made tool for removing starter
 

I used a small grinder to cut the Allen wrench so it would fit the top bolt & not hit the firewall.
This tool saved me a lot of trouble and frustration!

Here's another tip once you get the Allen bolt out throw it AWAY!
I replaced mine with a hex bolt .
That way you can use a box wrench to reinstall the starter. :)

Heres a pic. of the tool.

A two foot 3/8 extension with a universal and allen socket will give easy access to the bolt from the side of the transmission next to the transmission mounting bracket.
