Help!!! Changing 94 GS300 Water pump
 

I need to change the water pumpon my 94 GS300. I already have all the bolts out except for the stupid hidden one behind the Timing Belt pulley. Does anyone have any tips or know any tricks to move the pulley and get the last bolt out??? Also, is that why they sell both a 10-fastener and 11-fastener designed water pump?? Does the 10-fastener design not have the bolt that goes behind the pulley? Please get back to me ASAP guys because I am in the middle of the job right now....Thanks a million!!
