Thanks for all the information. My knowledge of the production process has improved by leaps and bounds in the past few weeks. In your last answer you indicated the T-birds spent about 36 hours on the line from start to drive off. I'm guessing then that the date the ROT is printed preceded the actual build start date. The two ROT's shown in this string show ROT dates of 11/10 and 6/19 and schedule dates of 11/13 and 6/23 respectively. The June dates include a weekend. This is a 3 working day duration in each case. I wonder if that is the standard duration?
