Vintage Speedster has parts that work. Guys have even found aftermarket windshield glass that fits several makes in that the chrome frames and uprights are the same. The hardware is fully interchangable, from bumpers, to windshields, to door handles and, my impression, door latches. There may be variations in hood and deck latches. The only area I would exercise caution is in body panel (deck lid, door and hood) replacement. I think those items may be fit/mold sensitive. I see the rest of it, from tops, to top frames, to windshield, to mirrors... as interchangable.
