My '30 Roadster rumble seat riser/platform has a factory punched hole at each end of the leading edge of the platform about 1 inch from the edge. I would assume they are to attach some type of stop pin or stud to keep the rumble seat cushion in place, but my car doesn't have the studs. I checked Bratton's website and they show the platform but no mention of any stud or pin for the holes:

Is there a specific pin or stud that should go there and where can I find them?
Appreciate the feedback.
