I have come across an oppurtunity to purchase a complete 1969 Mustang fastback. The car is running, complete and the body is straight. The interior is in very good condition as well. The downside to the car is that it came from Wisconsin and the undercarriage is pretty well rusted. The floor pans, torque boxes and frame rails have to be replaced. The floor in the trunk looks good and so do the fender wells and shock towers. I know what the cost of the sheet metal is but I have no idea how much work is involved to replace these items. I was hoping that someone here has been thru this already and possibly share some ideas. Thanx in advance.
