Were rear speakers available in a 66 conv.? where were they? Are they reproduced? Do thy sell a wire harness? Thanks

Don , this is just off the top of my head,Im sure of a rear speaker option in 67 not sure if it was available in 66 where one speaker was mounted in the trunk on the upper part close to where the motor for the top is located,It was mounted in a black box made of materal close to cardboard, the part # is 987056,as far as duel speakers I dont know.
