I spoke to my contact at Lippert and they informed that they did not start keeping a record of pin boxes until 2013. Therefore, the only way you are going to be able to identify what bolt pattern you have is by measuring the mounting holes using the attached photo. The most common bolt pattern is a 1621 which measures as follows:

2a: 7-7/8"
2b: 2"
2c: N/A
2d: 5/8"
2e: 15/16"
2f: 6
3a: 17-3/4"
3b: 25-5/8"
3c: 12"

If your measurements match these then the correct Trailair Flex Air 5th Wheel Pin Box for you is part # LC328492 for 18,000 lbs or part # LC369535 for 21,000 lbs.
