Yes Paul, I stand corrected. 61 Impala, and 61 Bel air 2 dr (bubble top), and 62 Bel Air 2 dr hard top (bubble top) are all the same size width, No speaker in the rear seat....Senior moment, as I used the rear seat from the 62 impala when Jim and I cut the roof off of the Impala and replaced it with a bubble top roof. When I reupholstered the rear seat, I welded a few cross pieces into the space of the rear speaker and padded over it when I upholstered it with the Bel-Air material. Get all of those restorations we did, a little mixed up at times!!!!!!!
