Crazy alignment problems

I was just telling the OP the easiest way to get the job done, using a 2 piece's of sheet metal is the easiest way if you don't have turntables.
That's how we used to align the late model stock car my friend had for years and it worked great. you could do it on the pavement but that is very difficult because the tire can't slide when it needs to, It would be easier in the gravel than on pavement.
