Side Rail Spacer Size for the Demco Hijacker 21

Question

Question:

I just received my new Demco 21K 5th Wheel Hitch. Am in the process of assembly and asking what size spacer 1/4inch or 3/8inch if any at all did you use when assembling the side rails? I have a 2017 F-350 Super Duty with factory installed 5th Wheel/Gooseneck kit installed. Im sure the bed on a 2015 or 2016 would be the same. Thanks
