These are some pics I took when I was working on the same. These are the rear half of a *fixed output* manual tranny & the front half of the auto tcase that would go behind it.








With the fixed output, you have about a 13/16" gap between the cases for an adapter plate. I do think it'd be a good idea though to cut off a half inch or so of threads from the rear output of the front case so you can get more spline engagement. You'll end up with a thinner adapter plate, but you can give up a lot of the 13/16" in that area. I did rough cut an adapter (no pics) and ground off a little of the rear output to close the gap enough that I could use 3/4" plate for the adapter. You could cut more and use 3/8" - 1/2" plate as well. That's still plenty thick and gives you better spline engagement.







This last one is two auto tcases behind a 4l60. This was just a mock up to check driveline length. It's way too long for an Amigo, but a Rodeo/Trooper could do it.
