Geez this side was a bitch! It took at least 2 hours just to fit that damn header in the right position. This side is so tight to work with. We had to continuously jimmy the header back and forth to finally fall into place. The worst part was actually bolting the header up. Make sure you have the last bolt in that last slot, because once the header is in place, you can't fit the bolt in that one. We found this out the hard way and had to rip it back out and re-install it. Pain in the ass!!!
