Exciting progress! I had no issues with any of the holes on the bell housing and the backing plate. It’s a little unclear from your post but some bolts don’t go into the Coyote but into the blocking plate and with a washer/nut on the back.

For torque specs, I normally check the expected torque for the bolt size, grade and pitch when I have conflicting information. Physics is physics. However, 60 ft lbs + 60 degrees sounds too high.
