"It's only long on one side". That's priceless!!! So, it's only 1/2 wrong; the other side is the correct length.
I'm trying to imagine how this could happen in the manufacturing process; and it eludes me. Therefore, there had to be a HUMAN BEING involved somewhere!!!.
I thing this problem has occurred before; and there is a fix, it is the "offset engine mount" which would raise the engine/motor, only on the long side not the short side
