Drivers Side Rear Spark Plug 440

with the engine at the wrong offset (none) your driveshaft orientation is wrong too as the trans tail is still at factory location. You always want to maintain a parallel output and pinion relation in any axis with a slight nose down attitude per your rear end setup, but skewing any off the X or Y is not recommended. Try and get it back to 1.25 offset and that will free up some spark plug room.
