Well I got the headers in and all the bolts tightened except for the last rear bolt on the passenger side. Any tips for getting that one? I might have cut the air tube out to get access to it. How was your y-pipe clearance? Did it touch anything?

 

That last bolt is a major pita with a/c. I used a small open ended wrench and went at it from various angles till I got it tightened. You could just leave it out. I did for a while before I had to remove them to do some work. My y-pipe clearence was kinda close but it doesnt touch anything.
