Hey 71, lots of a bodies in Georgia. Not too far from you. I was thinking though. Your car is solid except for the roof? I know you have a doner roof. Also you have taken the motor out of the car and its possible a little too much has been pulled out of your car and you may very well be overwhelmed with the amount of work the car needs. If the roof truly is the only rust put the donor roof on the car. I know its alot of work but do you know how hard it is to find a rust free a body these days ( I think you do now, anyhow after what I read). Get the motor back in that car and just drive it until you have time to get to the roof. You can get the motor in the car and have it on the road in a weekends worth of work. Look at the big picture here. A few years from now you will be kicking yourself in the butt. Just my two cents!
Chas.
