i'm in the process of installing mine. the 2 x 2 piping extends pass the rear floor and under the bucket seats. also when i cut the floor is it supposed to be flush all the way down or does it stick down.

 

I dont have any pictures but when I installed mine they are about half inside the car and half out, also one thing I didnt like is they dont actually connect to the rear subframe I bought some 2x2 tubing and some 2x2 angle iron and made it so the rear subframe actually conects to the subframe connectors If you want I will try and get some pictures up in the next day or so
