Wiper motor removal

[Stephen Hutchings <s.hutchings@rogers.com>]

OK, here's another stubborn item. When trying to undo the nuts 
holding the wiper motor mounts to the underdash bracket- I can see 
through the gaps between the rubber bushes that the bolt shafts are 
turning with the nuts. Because I haven't had to remove this item 
before,  I would appreciate any suggestions on how to separate the 
two!
