"Should be easy" Easy to say...
Those top bolts are tricky. The most important thing is to make sure you are in square, and all the way. Charmalu and I chewed on those puppys for awhile
I think the way we got one side was with a allen socket and long extension; with the motor jacked up ever so slightly, giving just enough space to work around the IP side, to get the tool in. Incredibly tight working space...
That jacking the engine thing up is subtle too; seems you want just a little bit to take pressure off.
When we thought the hard work as over, and finally time to bolt down the new bolts (top first, then large bottoms), we found the holes would not line up. the solution in my case was to drive the car a bit to align them! Others have reported just lowering the engine and starting and putting into gear helped them. Of course, you want to be real careful your power steering belt doesn't chew through an oil cooler line...
Good luck! Don't give up; they will come, just don't rush and strip.
