Well I talked to the original owner today. As I suspected he had no idea the front clip was changed. It must have been done after he sold it. He's just happy to own the car again. So he just wants to leave the 73 front clip on it. He plans on driving the car. I'm just going to fix the problem areas then hang quarters and paint it. This is the driver side floor pan all done.

After
I still need to add the seam seller. I will do this after I finish the passenger side.
