You are looking at the back seat from a 57 Chevy 210 2 door sedan. Correct for 55 to 57 Chevy & Pontiac 2 door sedan only. The base measures 62 wide and 21 deep. The backer is 58 across the bottom, 56 across the top and 26 tall. They will not fit 2drht or convertible. The covers and padding need replaced. What you are actually bidding on are the upper & lower frames for re-upholstery. The frame on the base is a little thin on the bottom. It will require some repair. Otherwise solid. Next to impossible to find. A great core for re-upholstery.
