Need Help!

We just put my 318 back in my Duster today and encountered a problem. The block went in with the transmission. First we had a hard time getting the engine to sit in the passenger side motor mount. We finally got it to go in. Then we noticed that the transmission wasn't straight. It was off a little to the left. I am 99% sure the motor mounts are where they should be and on the right sides. Does anyone know how this would be straigthen out or why the block and transmission would be pointing slightly to the left. Anything helpful would be appreciated. Thanks
