ANSWER: It is not welded backwards. That is an older designed anti-tilt bracket. The new design does not have the flanges wrapping around the receiver hitch.
The old design had the flanges wrapping around the receiver. However both design still do the job. Both brackets must be used with the bolts on the bottom. The bracket is designed to work with gravity. By installing the bracket, upside-down the bracket is working against gravity and lifting the weight of the carrier and motorcycle. This improper use can stretch the metal of the VH-070.
