We’ve got a 2018 X 100D with the towing package. I’m working on getting ready to tow a small Airstream trailer, have the braking controller, but I’m trying to find the right shank and ball to go into the receiver (2” type). I ordered one I thought would fit the bill, it was supposed to have a 3/4” rise, and seemed like it probably was about 8” from the pin holes to the ball hole (based on the overall length stated.) However, it just arrived and the lift is more like 7/8” or an inch, and the distance between pin and ball hole centers is 8.5 inches. Both of these are more than stated in the Model X manual. Here is the drawing from the manual, and a photo of what mine looks like (see the dimensions I stated above). Is mine actually usable even though out of range? What model and manufacturer shank are other X owners using? (Mine is Connor 1623210)
