just picked up a hard dog m2 roll bar but it did not come with any bolts. i am going to get them all from home depot and just wanna make sure that will work as long as i get grade 8 bolts or higher. also does the sheet of metal that goes under to sandwich it need to be bent or can it be just a flat piece of steel. and one last question...when moving the seatbelt to the bar do i need to get any special mounting piece to let it still be able to move and not get loose. thanks
