diff pad set up
assuming street car. from what I remember and my understanding is that you need between 1 and 3 degrees tops. 1 1/2 degrees down at the trans, it should be an equal but opposite amt at the Pinion - 1 1/2 degree up to keep proper joint angle.
Second is the interior is gutted? need weight compensated as it will change the angle once added. I think your angles are off.
steering wheel is right drive cool!?!
someone else should chime in here. So here a bump if nothing else.
