First drill a hole throught the center of the bracket that wraps around the Steering Column
Then mount the turn Signal Switch to the Steering Column
I used a center punch and then Drill a small pilot hole through the center of the wrap through the Steering Column
Use a sheet metal screw that taps it's own threads and screw it through the pilot hole and tighten it up
I chose to locate the Turning Signal Switch a bit up from level so I could see the light on the switch through the spokes of my steering wheel ..
thx to Carl52 for giving me the measurement I needed so not to use too long of a screw,, so not to interfere with the inside shaft that the sterring wheel is attached to
