Tow hitch for A-bdy Cuda

Can anyone direct me to the owner of a red '68 'cuda F/B that tows matching '68 'cuda trailer?

There are pics of the car and trailer in RedFish' Photobucket account at this link, http://s102.photobucket.com/user/Ob...w.html?&_suid=1377560753283030557622522183675

RedFish told me he saw the car at a show in Commerce, GA a few years ago, and that he believes it is from OH.

My interest is specifically in the tow hitch. I would like to know if it was owner built, purchased, plans available, etc. Any help will be greatly appreciated.

Thnx in advance,
