Ya I was checking your pictures out and now that's why I'm question ing what I am doing. But setting here looking now the engine is on a reward slant its the intake the way its made its a little higher in back. I sorta understand the degree angle thing. So the way truck set check degree at back of tranny and make yoke at rear end 2 degree opposite. Does this with frame level or the way truck is going g to set? Thanks for help.
