Hey David, congrats on the new trailer. In order to identify which gooseneck pin box is the correct one for your 2026 Brinkley, I'll need you to email me a picture of the sticker that's attached to your current pin box. The sticker should say date of manufacture, weight capacity, and have some form of RPO, LCI, or serial number on it. If you could email me a picture of it or carefully put all that information where it says Reply to Jerred H, I can find the right gooseneck pin box for you. Also if yours says Turning Point or Rhino Box on it let me know because those bolt patterns are easy to identify replacements for.
The Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box item # GY38FR, you were looking at fits a Lippert 1621/1621HD bolt pattern. That bolt pattern information has to be looked up. You won't find it on the manufacturer's sticker.
You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them. If you're emailing me a picture go ahead and send it directly to the address you receive this response from.
