Duster Roll Bar on Ebay?
Art Morrison for mine.....they have an option to keep the rear seat by routing the rear tubes through the package tray. Priced in line with everyone else.......if I had to do it over again , I'd probably go moly. I used their 10 point cage and the car is stiffer than a honeymoon prick , but definitely added some mass. They also have options of front tubes going behind or through the dash.
