Off-road X-pipe install PREP '91 coupe 5.0 5-speed

Hi all, I took everyone's advise and ordered a BBK off-road X-pipe. I'm wanting to do this myself and I want to be prepared. I am going to soak the existing bolts with PB Blaster every night all week, and I know about that pesky passenger side manifold bolt, so my question is, with having only a basic socket set, what type of tool do I need to get to that hard-to-reach bolt? (be specific, I'm no mechanic) my 91 coupe has stock manifolds, and I really don't want to snap a stud. Any help and experience is appreciated! I have another 2 weeks before I am tackling this, so I want to prep as best I can for now to make it smooth as possible. Thanks!
 
A wobble attachment and an 18" extenstion will make the job very easy. This is just a "nuts and bolts" project, not rocket science. A basic socket set and a little patience is all you need.
