If you have ever handed your keys to an 18 year old tech who has that 'I'm lost on this one' look in his eye you will know the value of the info above. It's priceless. I took the 1st 69 that I rebuilt to a Rowleys that specializes in front end alignment. It was just after I finished it. I hadn't even drove it 5 miles yet. He spent an hour on it. I noticed the owner of the place was hovering around. When the car was done the owner took the keys and test drove the car. He was gone for 20 minutes with it. He pulled in like nothing was amiss. He charged me and I was on my way. The car pulled to the right and the steering wheel was crooked when going straight down the road. That was exactly how it was when I drove it there. Since then, I do it myself. Never again will the owner of a Rowleys get the first test beat on one of my projects!
