Hey Matt, congrats on the new 5th wheel trailer. Do you know what pin box is on the Brinkley Z3100 you're buying? There's quite a few different bolt patterns and there's no database that shows me what pin box is on a trailer.
The Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box item # GY48GR you were looking at will only replace a Turning Point pin box. Now those are typically clearly labeled as being a Turning Point. Rhino-Box is another one that's easily identifiable.
If the trailer you're buying's pin box isn't one of those two, I'll need you to get me a picture of the white sticker attached above where the pin box bolts to the 5th wheel trailer. It'll have information about the date of manufacturer, weight capacity, RPO, LCI, Serial number. If you can email me a picture of that or just put all the information on that sticker where it says Reply to Jerred H, I'll be happy to find you the right goosebox.
