The Trailair Rota-Flex 5th Wheel Pin Box - Lippert 1621 or 1621HD - 18,000 lbs # LC328330 does require capture plates for the Demco Hijacker autoslide that is similar to the Pull Rite Autoslide you have. The measurement from the front of the plate to the king pin is 4-1/2 inches. The overall plate is 11.387 inches by 12.655 inches.

I was able to research for you that the Trailair Rota-Flex 5th Wheel Pin Box - Lippert 1621 or 1621HD - 21,000 lbs # LC328329 will require the 5" measurement from the leading edge to the king pin and will use the capture plate number 331760 for your Pull Rite 5th Wheel Hitch. You do not want the 5-3/8 inch plate number 331756.
