Drivers Side Rear Spark Plug 440

Right now it is just setting on 1 bolt through it all. As I mentioned, it will need spacers for and aft of the motor plate. The trans is bolted onto the mount and the mount in the crossmember so I dont know how it would move fore or aft.
I modified my crossmember by adding 2 inches, this allowed the Engine to move back towered the fire wall, tight fit but worked well. just modify the trans crossmember?
