Working on my quarter panel install and alignment. I’m shooting a level/straight line with a laser level. Question is how “straight” is the body line really? Anyone ever shot theirs and checked it? nothing on my car is “straight” anyway so hate to ruin it.

I have done a similar process for aligning body panels. I used a self leveling laser with a single dot. I rotate the laser on a tripod to go along the body line. I have new quarters and original doors. The line on the new quarters moves a little up over wheel wells, less than an 1/8".
I have wasted a lot of time on front fenders, as I was working with original fenders both had been worked over many years ago, so I was not sure where body line went. I recently bought new Goodmark fenders, and carefully found the line. They are black and I sprayed a grey primer stripe on them along body line. This allowed me to see the crest of the line better. I used a pencil and marked the crest every 4" or so, and then I used a straight edge to connect the dots. From what I was able to determine, the line in front fenders starts to dip 9" behind the back of the side marker opening, over top of the wheel well. Then it dips a little more 3 or 4" back from front edge. I was trying to get the line at the front of fender up to the laser, but I was getting a huge gap at lower front of door.
