I have a Demco "Kwik-Tow" tow bar that I mount to my D-ring tabs. The width is adjustable and the arms fold completely together for storage. Because the tow bar has 1/2" holes and the tabs have 3/4" holes, I bought some flanged brass bushings with 3/4" OD and 1/2" ID to put in the D-ring holes and 1/2" bolts (grade 8) with nylock nuts and washers to bolt it together. Works great for me.
