I am mid-process in removing the water pump from my 1996 Bonneville. (It is not the SSE.) The left-most bolt can only unscrew about 1 inch, then it bumps up against one of the pulleys, I'm not sure if it is just there to take up slack, or if it is the harmonic balancer. Well, I need to remove this so I can get the last bolt out of the water pump!!!
Any help?? What is it? How do I remove it?

I have the Chilton 28200 book, and it is near worthless. I decided to do this job myself as the description is basically "Remove the bolts from water pump. Scrape away old gasket. Install new pump."
They fail to mention that 1 screw is blind (I had to do it by feel) and that this last one cannot be removed unless I remove this other thing!!!

HELP! PLEASE!
thanks!
