It is a long and complicated story, but the bottom line is that Lippert mislabeled my pin box at the factory. The sticker says it is a 1621, but it is actually a 1116. I guess I'm better off, the weights are 15,500/19,000 respectively for the 1621/1116.

If anybody is going to get an air pinbox, or change pinboxes, this is worth checking out to be sure you get the correct replacement.
