My dad just gave me his 67 camaro to restore and the car is in pretty rough shape from sitting outside on the farm for 10 years. The car has been rear ended twice since my dad has owned the car. My dad had the frame straighten from the two accidents, but never had the time to do any of the bodywork on the car. My questions is how hard is it to replace the rear frame rails my self or is it better to have someone else do it for me?
