Thule rack feet for an open M416 trailer?

Hello, does anyone know what Thule feet will work on an open top M416 trailer? I have bars, I need to know if there are any feet that will work on the round edge of the top, the taller, the better. I need something until I can get my lid built. Thanks for your help.

How about bolting on artificial gutter sections? Link to them https://tinyurl.com/y728gq57

Thanks, I will have to look into that. My only concern; the lip is round rolling to the outside like a P, I am not certain that would work. I believe that I have read where one of the threads, used some feet that could go directly on the lip of the trailer but after hours of searching, I couldn't find it.
