I went out and bought a digital angle gauge from Harbor Freight today. I verified it against a bubble level and my gravity gauge. I'm confident it's accurate within a couple tenths.
Pinion is 3 degrees nose up. Drive shaft is 1.5 degrees rear end up. Tail shaft is 3 degrees down.
Numbers are a little better I'd say but still not good enough if working angles are to be below 3 degrees.
I'm not sure why the drive shaft angle is less with the digital gauge. I put the gravity gauge right next to it and it went right back to the 3 degrees I measured the first time. I'm going with 1.5 degrees.
I'll adjust the angles in the coming days and see what happens.
Thanks
