The 69 has what I think are fatigue cracks on both rear foot wells just ahead and parallel to the rear torque boxes. I am going to take the car in to a Mustang body and frame specialist (Marlo's in Chatsworth, CA) for an inspection and plan a course of action but of course you guys get first shot! Are there alternatives to replacing the floor pans? Are repro floor pans as good as original? There is a 70 coupe in a nearby junkyard, would harvesting those floor pans be a good idea? Is there any alternative like gusseting and welding the area of the cracks that is not too, well, bush-league? Thanks for any and all advice!
