Questions on recent alignment

Recirculating ball type gear boxes like on our old Mopars will try to find center when the pump is energized. So, if the steering wheel is off center say to the left a little, it is completely possible the slight pull to the right is the gear box trying to find center.

When you say "offset" is .7 are you saying one side is .7 of a degree different than the other as far as caster? That's unacceptable to me. I like caster as dead even as I can get it. I don't care about road crown or any other road anomalies some shops try to compensate for. When I am on the interstate, or drag strip, I want my junk driving straight. 0* camber is perfectly acceptable. Anywhere from -.5* to +.5* is good, but again as long as it's even from side to side or close.
