Ok guys this is what I know. Gm has or had stopped the production of the 69 convertible reproduction bodies. There is a company in NC that makes a conversion kit that you take a 69 coupe and make it a convertible. It is alot like what CARS, Inc was doing with 57 4 doors turning them into convertibles. I know that Ed and crew over at 21st century have all of the pieces to do the conversion and a the car that they are doing is on the table. The company that is making the stuff is called Dynacorn. So with all of that being said.
