Too much here to analyze tonight. but, I OWN A 65 Ambassador convertible. There is NOTHING light about the bracing on this car! NOTHING! Like I said, it can be jacked up on one corner and you can open and close the doors with zero signs of flex. Cut the roof off a car and see what happens. Mustang or Rambler, it'll bend. Tha Ambassadors got a massive box "frame" running the entire length inside the rockers. Corner bracing at the cowl, under the rear seat, up along the rear of the doors. Theres a bunch of pieces. Some of it could br added to any hardtop body. Some of it would take a major dissection to get in there. -- Mark Price Morgantown, WV 1969 AMC Rambler, 4.0L, EFI, T-5 2004 Grand Cherokee Laredo, 4.7L, Quadratrac II " I realize that death is inevitable.
