The reason I said seats won't work is beacuse there is nothing to to bolt them to. The front seats have reinforced brackets that are nearly impossible to break off. And aftermarket seat brackets bolt directly to the existing points to make them safe and secure. Rear seats don't have anything like that. Most rear seats have a couple of hinges that are reinforced, but there isn't any good way to mount a seat on to that. And don't even think about just drilling into the floor. It's too weak. The floor will bend under a strong impact sending your passenger flying.

Aside from the physics, think about the legalities. You are mounting a custom seat into an area that's not meant for it. If you are ever in an accident, and one of your passengers is hurt by your custom mounting, then they can sue you for damages. Any good lawyer would eat that up. The reason that this doesn't happen for front seats is the same reason I already mentioned.

If you REALLY wanted to do this, you would have to have a shop add lots more sheetmetal to the floor of your car and build an OE style mounting bracket. Then they have to make the seatbelts work with the new seating location. That's hella expensive and not worth the work. There's a reason nobody has done this before.

There are a lot of things that are great to fab up. And I say go for it. But some things you really need to leave to the professionals. Setting up seats and seatbelts is one of those things. There is way too much risk involved to skimp out on those details.
