When we restored 5r002 we did put the door tag on it just like 5s003 and 5r001. We had that picture (and more) and we knew it should be there. for some of those shows where we had to leave the car outside, we removed it so it could not be stolen.
As to the timing of the placement of the under hood tags, during an interview with Jerry Schwarz he indicated the he in fact put the 3 Shelby number plates on the cars. He said that when they were moving to the LAX facility they needed to move a large number of cars (approx. 40) to the new location. They hired some temporary workers who had drivers licenses to move the cars to LAX. The next morning one of the cars showed up missing. They were supposed to have all the data plates attached to the cars before they moved them but not all of them were attached and these first three cars were still sitting over in the corner and did not get the data plates put on. That morning Jerry said he could hear Carroll Shelby yelling in the office and the next thing he heard was "jerry come to the office" over the intercom. He thought he was in big trouble and when he entered the office he saw Carroll standing there with three data plates in his hand and he said "get these put on those cars before they move them". Jerry said he went over and got his pop rivet gun and put them on the cars with out any regard to which car was 1st, 2nd, or 3rd, and that is how they were misnumbered.
When Jerry told this story at the banquet at SAAC 39, Ted Sutton spoke up and said the car that was stolen was a cobra but some of the others had never heard that story about the stolen car. Jerry thought the car was Mustang.
We were pretty confident that the date was sometime around the end of January 1965 but someone else might have an exact date...John Brown
