Quote: Fear wasn't enough to keep me from clicking on this. I wish I could help , but I am struggling to decipher your angles and how they relate to flat level ground. There seems to be an information overload. You can get the pinion angle from the tail shaft and pinion yoke angles alone..........yes ? Or maybe I am more confused than you are.
2 theories ... one uses pinion and trans the other uses pinion and drive shaft... now days I just ask which answer would you like... I dont care to get into all the BS... I happen to use the drive shaft but when I built the car I put the trans on centerline with the pinion
