David,

I use a big screw driver to pry between the flat bracket and the case pull
towards the passenger side.

Or do what I did. I had a bracket modified by welding in a piece from a late
model Golf bracket. It's the one with teeth which engages a cogged washer.
The action of the washer against the teeth on the bracket does the tightening
for you. People with inline VW engines would know what I'm talking about. I
don't know why VW never applied this to the Wasserboxer. No more prying and
no more crying (from busted knuckles).
