When you say "off" you mean the pinion left/ right centerline? That is likely normal as long as the shaft has room in the tunnel
I think 3 down is too much with the trans down. Look at it this way. If the trans was leveled (0 degrees) you would have to jack up the rear of the car. This would put the pinion FOUR down. Do you think it will "wrap" enough to get from 4 to zero? Doubt it. I hear "talk" on here about the pinion 2 or so down. Wish I had an unmolested car to check it LOL
