OK, I raised the Coronet up on a 4 post hoist. Jacked the front end up so the drive line is level at 0°. The transmission slip yoke is 2.5° down (negative). If I understand correctly the pinion should be parallel to the slip yoke. The thing is the rear end is higher than the transmission. So the only way to make the pinion parallel is to have it 2.5° up (positive).

Let me ask, simply. With the drive line level at zero degrees, trans down 2.5°, what should the pinion be at...keeping in mind the rear end is higher than the transmission? Down or up? I didn't think that the pinion should be positive.

I have Schumacher engine and transmission mounts. There's no way to raise the transmission. No room. And if I raise the rear of the car it will look like a stink bug.
