I just got a bestop safari top for my 2 door, and I read the instructions on how to strap it up... BUT in the back I have 2 different straps, and the instructions only show one. The ones on the back of the top pull down and wrap around the seatbelt brackets and go back to the plastic buckle on the corner... right? Well I have another strap there too that has the click in buckles on each end.... WHERE DO THEY GO? Anyone know? Thanks.
