Hi Josh, I did some research on that frame of yours. I was sure when I posted my last reply about my own cars but I wanted the get the official GM word from my chassis manual. This is an excerpt right from that manual. All extended station wagons, convertibles, 84 and 8600 series use the boxed type frame, meaning that the side rails are boxed or two sided in the centre section of the frame. All heavt duty frames are the boxed type contruction using the same steel stock as the convertibles of the same series. The series of your vehicle is a 35800 which indicates a delta 88. 38400 is all ninety eight models except luxury sedan and 38600 is the series for the luxury sedan. YOU ARE LOOKING FOR AN 35800 SERIES DELTA 88 FRAME. I do think but do not know for a fact that a Dynamic 88 CONVERTBLE frame will work. The frame that I have would have to be reinforced in the centre section (I would not do it if it were my car). I have done a frame off restoration on a 66 Delta 88 Holiday coupe. Every nut and bolt. I own a 65 Starfire and I am beginning a frame off restoration on a 66 Cutlass and of much lesser importance I own a 78 corvette. I hope I have helped you along. This is correct information.
