I worked at the Atlanta plant in 1953 on the body line and I can assure you that body parts were not assembled "loose" for later adjustment. Some plants dropped the body first and then later fitted the front sheet metal. The Atlanta plant did it the way your picture shows.Could it be that at that factory everything was assembled "loose" and then the hood was added and THEN it was all fit together? Wonder if that car is still around today.When I assembled my front sheet metal that's what I did.
Here's a picture of a friend of mines 40 coupe coupe taken in 1948 when we were in high school. He sold it in 49 and had a lot of old Fords since. He passed away several years ago and his son who has several old Fords emailed me this picture. G.M.
