I bought it from Complete Off Road 5 years ago. The mods to the cage include 1/4" plate under all three seats. It helped with mounting, seatbelt mounts and makes sure that if the body (fiberglass) comes apart from the frame that the seats and cage will stay together. I also took the rear hoop and moved it forward to allow head clearance for the rear seat, I had to shorten the two pieces of tubing between the hoops to move it. Other than that I mounted reinforced gussets into the uprights for the shoulder belts and some small corner gussets.
