Our hidden bolt rollbar mod. We used 1/8" plate to make the circles and used a 1/2" grade 8 bolt and nut. We drilled 1/4" holes in the roll bar to weld in the circle plate with the bolt in. Also a picture of rollbar trim rings we cut out on a cnc router. We decided we wanted to make our own that didnt have any screw holes in them. Last picture is of the pins we will use to hold the rollbar in place.
