A-body Frame & body mounts

How to measure your frame for square and twist. This is what I do. I measure from point A to point B on the body mount holes in the frame. they should equal the same from left to right and right to left. I check the frame for Twist. I go in the back and I measure down from my shock holes. First I make sure it's level then when you measure down it should be the same on both sides.
