I didn't have a swing away. What I did was cut the tongue off, about 14" back from the hitch. I put some square tubing in the hitch end and welded it to that piece. The OD of the incerted piece was the same size as the ID of the tongue. I used a 2' welding 12" inside the tongue. The other side slid into the trailer. I drilled a 1/2" hole through that piece and used a pin and key, just like the reciever on a pick up. Any one can carry a few bolts, swing your tongue back and drive away. Or the tongue has been bump and rips your garage door apart when you open it.
