What Lippert Pin box is this?

[AddictedOffroad]

I have a 2011 Keystone Cougar 293-SAB that I just bought. I am wanting to upgrade the pin box to a Trail Air air ride pin box ASAP. However, I need to know which one to get and cannot find anything in any of the original manuals or documentation that would list what pin this is. Its definitely a Lippert pin box, but the part number does not cross reference to any unit I have seen.https://uploads.tapatalk-cdn.com/20170308/6b916e0218b91f2613b1dcf607280dd1.jpg

They weren't able to look it up, but after measuring everything it appears that I have the 15,500lb 1621
