I'm restoring a 1970 Mach 1, thought I'd share photos of the progress. Hop e you like the pics: new rear torque box patch installed: Rear floor pan extension welded in: New floor support welded in: New torque box installed: New toe board: Full floor pan: The car: Next comes the driver's side . Should be easier as we bought the car after someone already cut up the passenger side. Also, the driver's side is a little less rusty. I figure I have between 30-40 hours into the passenger side.
