1998 Ford Contour Q&A

1998 Ford Contour Question: How do I remove the pipe bolt from the EGR valve?

I have a 98 ford contour SE (6 cyl). I want to clean the EGR valve and ports but how do reach the bolt on the connecting pipe to get it off? I was able to remove the mounting bolts, but can't get a wrench in for the pipe nut. -
