all of the metal is good from the lower body line up the rockers doors front fenders ect. are all good, and i was thinking about building a frame like this one

which would get rid of frame rails torque boxes and i could build a support and aprons like he did too. then all i would have to do is floor pans and quarters
then there is the possibility of converting mu 69 coupe to a fastback i have done it before with a 67
