Expert Reply:
The Trailair Rota-Flex 5th Wheel Pin Box - Lippert 1621 - 21,000 lbs # LC328329 will mount on the standard 18,000 lb 1621HD frame with one hole modification. The actual trailer capacity won't increase, so you may want to stick with the 18K Rota-Flex # LC328330.
I reached out to my tech contact and the 1621 pin box does have one hole that is slightly different than the 1621HD. The lower front hole is higher on the 1621HD box so you would need to drill one hole on each side of your mount to fit the Rota-Flex 1621 pin box.
