Ted assembled these photos to highlight the differences between three different adapters: the Welliver, Floy Fox, and Rapport. You can learn more about adapters here: http://www.ewillys.com/2017/04/05/dual-wheel-adapters/
Ted’s also got a variety of parts for sale. You can see them all here:

Ted writes, “I changed over from a set of Wellivers on my rear of the 2a to a set of Rappaport’s. The Welliver’s are very rare and nice in the fact that they fit on front or rear of Jeep. The third type I have are exact copies from an original set of Floy Foxs that I found on an old Willy’s Truck many years ago. A good jeep buddy of mine, who’s a really great machinist, makes them for me when he’s not booming with his other work. All three of these types bolt right up to original Willy’s rims and, importantly, do not require the second wheel to be mounted backwards like on the Hickey type and shorter versions like the pair that have been on ebay forever. I think the Willys’ guys are smart enough to see there too short .”
