Molileortho: I'm putting bear claws in my 52 right now (my 52 has swing down handles from factory)I followed Houston54's write up but I put the pulley at the front of the door just above the top hinge (that's the real hard part) I modified the inside assembly by cutting the end and attaching a spring piece to it because I found the latch to touchy. I drilled a hole about half way down the arm to attach the cable and made an L piece to drop down in front of the inside assembly for power door lock because the bear claw lock wouldn't allow me to lock the door and close it. The outside handle shaft was cut to 1.25" squared and tapped for a 2.5" arm and a spring attached to keep the handle up. Hope this helps.
