satellite engine in a duster, advice?

Like i said before, i did this swap in another duster a few years ago. It was a nightmare. I tried the schumaker mounts on the /6 kframe, also had a 318 out of truck. nothing went smooth. I was hoping to just find a 318 from an a body but they are hard to come by, i was surprised to find one still in a boneyard in a satellite.
