Are you talking about the device that aligns the motor mounts / tranny mounts? If so, if you have a welder and drill, you can make one fairly easily. I built one a couple of years ago. Essentially all it is, is a chunk of steel tubing with a flange and a couple of holes drilled in it.
Somewhere in the archives is a post that describes exactly how big, how wide, where to drill the holes, and what size holes. I found the details on here when I built mine. The post will be about two years or so ago.
