428, My best advice to you is to enlist the help of someone who really knows what they're doing. Not just one of your buddies that says "Hell yeah, that's easy". I played with aligning my panels for an entire day thinking it wouldn't be that hard. Finally I had my brother, who is an expreienced bodyman, come down. He had everything perfect in a couple of hours. It really helps to know what a lttle pull here and a little tug there will do for the alignment. Believe me, trying to figure it out yourself for the first time can send you to the looney bin. Or your local watering hole for a long night.
Good luck.
