Installing engine and need help.

Ok so I am trying to install my engine and for some reaons it keeps looking off center. I am putting a 360 back into a 75 duster, but I do not have the spool mounts I have the older style ones because of new k frame. When I look at the mounts the seem to be crooked also. I am begining to think maybe my brackets on the engine are on wrong or am I just putting the mounts on wrong. I just can't figure it out.
