I think someone has been enjoying their Saturday night a little too much...unlike us...I feel my age!
I just installed mine Friday and it took all day by myself. I have one of the first 05's off the line (built in '04) and my K-member didn't line up correctly. Unfortunately working alone made this tougher than it had to be. I am so sore from wrestling the thing. The worst was rounding off one of the 18mm nuts that holds the k-member in by the shock tower and then needing to use an angle grinder to cut the nut off.
Long story short, my engine and engine mounts were about a 1/4" off fore/aft also. I had to kick the jack holding the engine until it was close, then kick the k-member back a little on the drivers side, passenger side was lined up correctly from the start. I finally used a long extension to hammer in the bolt from above. Since I have the Saleen supershaker, I took a lot of time tring to line the motor up to the hole in my hood and I am still about 1/8" off. If you look at it long enough you will notice it.
On a side note, how did you guys with long tubes tighten up the right side engine mount bolt and torque it? I ran the bolt up from the bottom and had the nut on top. I then used two wrenches and slowy tightened it up. It took forever. I tried using a wobble extension along with a univeral and still couldn't reach the nut or bolt from either side.
No issue reaching the top motor mount bolt with kooks longtubes. Had trouble with my jba shorties though.
