5th Wheel Pin kit for Running End Dump

You could contact the manufacturer of your truck with the VIN and they can tell you what it came with new or ask them for a copy of the original build sheet. I contacted Peterbilt in Dallas as that's where my truck was built and got the information that way. My (Fitzgerald) dealer was as useful as teats on a boar hog.. Keeping in mind that it could have been changed but more than likely has not been.
