Kankel have you considered a rubber/foam wedge to fit if caught in the rain to stop the rain running down onto your knees? Where are the seatbelts?
Not a major concern here in California and I did not want to clutter the look. would probably weld an angled barrier to the mounting plate to redirect water, if that was an issue. Removed the seatbelts a long time ago, I think they are useless in this application and treat this car as a motorcycle and ride accordingly. (It’s my personal choice, I am not advocating for anything).
