I know this is an old thread but...
I just did this a few minutes ago on my '94 RT/10. First, it's a very easy procedure and second, you don't need any tools at all to do it.
Simply grab the bottom of the seat cushion near the side-bolster support and push it towards the center of the seat. Look into the resulting gap between the seat cushion and the plastic seat back and you'll be able to see where the metal brackets are kind riveted to the seat back. Grab the cusion as close to that piece as possible and push it harder towards the center of the seat. You'll hear a pop as the wire seat frame comes loose from the bracket. Now do this in the same position on the other side of the seat.
The next set of brackets are just to the right and left of where the top-most center portion of the seat opens up into the pass-through hole below the head rest portion. Pull the seat cushion to the side again and locate the bracket. Once you have, push that piece of the cusion towards the center of the seat and they will pop loose just like the lower ones.
Once those four are loose, tilt the bottom of the seat cushion outwards and push up on the whole cushion. This will release the top bracket in the head rest. If you have trouble with that, push the head rest portion out some so you can see where the bracket is. Locating them helps you know where to put the pressure.
Takes about 2 minutes to get both seat backs off with no tools at all.
