Ok let’s try this. The angle finder used is digital. It compensates for opposite facing surfaces.
I would not put a lot of stock in the crank angle because it was coming off the bolt head. The best numbers are out put shaft and pinion. The pinion is definitely nose down over 4*. I shimmed up the tail shaft and reduced that angle of trans to less than 3*. The driveshaft has been ordered based on the trans joint angle will be around 2*. The pinion angle is now closer to 6.5*. The trans is clear up into the tunnel and cannot go any farther without interference. HIt looks right.
