As i said...I much woulda rather woulda done the rotate with my truck present but i was doing it at school where theres no room for my truck for more than one day. and I dont get to work all day on it. We have a few hours of class time each day. Unforturnatly i had to work with what i had but everything tunred out great and my measurments and angles were spot on for what my applicatoin needed.
