problem replacing water pump in dynasty
 

Hey all,

One of the bolts sheered off on the water pump when taking the old one out. there is about 4 inches from the bolt that i need to drill out to the fender well. What tool should i use to drill this out? tried a 90° angle for drill and didn't fit is there any other tool anyone knows about? what about taking something off the car to gain more access? Thanks in advance.
